3 E58856 Things never will be same the E58880 The original has set a new standard for power circuit breakers around the world. Over the years, other major manufacturers have tried to keep up by developing products incorporating s most innovative features, including the breaking principle, modular design and the use of composite materials. Today, continues to innovate with the new Merlin Gerin NT and NW ranges. In addition to the traditional features of power circuit breakers (withdrawability, discrimination and low maintenance), now offers built-in communications and metering functions, all in optimised frame sizes. NT and NW incorporate the latest technology to enhance both performance and safety. Easy to install, with user-friendly, intuitive operation and environment-friendly design, they are, quite simply, circuit breakers of their time. 1

4 E58873 The ultimate power in power distribution New, new levels of performance Five performance levels N1 - for standard applications with low short-circuit levels. H1 - for industrial sites with high short-circuit levels or installations with two parallel-connected transformers. H2 - high-performance for heavy industry where very high short-circuits can occur. H3 - for incoming devices supplying critical applications requiring both high performance and a high level of discrimination. L1 - for high current-limiting capability and a discrimination level (37 ka) as yet unequalled by any other circuit breaker of its type; intended for the protection of cable-type feeders or to raise the performance level of a switchboard when the transformer power rating is increased E58868 Integration in a communications network can be integrated in a general supervision system to optimise installation operation and maintenance. The communication architecture is open, and may be upgraded for interfacing with any protocol. Switch-disconnector versions The switch-disconnectors are derived directly from the circuit breakers and offer the same features and performance levels. They are available in HA, NA and HF versions, depending on the models. The HF version includes instantaneous protection to prevent closing on a short-circuit. Once closed, the switch-disconnectors are unprotected and behave like ordinary switches. They are often used for busbar coupling. E V and 400 Hz distribution systems The range can be used on 1000 V installations (mining industry) and 400 Hz systems (aeronautics, computer centres). 2

5 Thing will be never the same 3 frame sizes, 2 families NT 800 to 1600 A The new range of power circuit breakers includes two families: c NT, the world s smallest true power circuit breaker, with ratings from 800 to 1600 A; c NW, in two frame sizes, one from 800 to 4000 A and the other from 4000 A to 6300 A.

6 E58869 No other offer can put us in the shade Optimised volumes E58879 The smallest circuit breaker in the world NT innovates by offering all the performance of a power circuit breaker in an extremely small volume. The 70 mm pole pitch means a three-pole drawout circuit breaker can be installed in a switchboard section 400 mm wide and 400 mm deep. Practical installation solutions E58880 E58881 The new range improves upon all the installation solutions which have already made a success. It has been designed to standardise switchboards, optimise volumes and simplify installation: c incoming connection to top or bottom terminals; c no safety clearance required; c connection: v horizontal or vertical rear connection; v front connection with minimum extra space; v mixed front and rear connections; c 115 mm pole pitch on all versions; c no derating up to 55 C and 4000A. Optimised volumes Up to 4000 A, NW circuit breakers are all the same size, the same as the old M08 to 32 range. From 4000 A to 6300 A, there is just one size, much smaller than before. Retrofit solutions Special connections are available to replace a fixed or drawout M08 to 32 with a NW, without modifying the busbars or the door cut-out. 4

8 E58878 The shortest distance between two points Innovation E58875 Greater dependability Filtered breaking The patented new design of the arc chutes includes stainless-steel filters. The chutes absorb the energy released during breaking, thus limiting the stresses exerted on the installation. They filter and cool the gases produced, reducing effects perceptible from the outside. Filtered breaking Automatic unlatching The automatic unlatching of the circuit breaker operating mechanism for high short-circuits extends performance up to 150kA. It produces ultrafast tripping for all short-circuits higher than 37 ka (L1) and 65 ka (H3). For lower short-circuits, the system does not react so that the control unit can provide total discrimination with downstream devices. More intelligent trip units E58874 Today, with the high speed of calculation, the small size of memories and advances in miniaturisation, trip units have become circuit breaker control units offering increasingly powerful functions. They accurately measure system parameters, instantly calculate values, store data, log events, signal alarms, communicate, take action, etc. The new ranges, equipped with Micrologic control units, constitute both an extremely reliable protective device and an accurate measurement instrument. User friendly Intuitive use Micrologic control units are equipped with a digital LCD display used in conjunction with simple navigation buttons. Users can directly access parameters and settings. Navigation between screens is intuitive and the immediate display of values greatly simplifies settings. Text is displayed in the desired language. Navigation buttons on a Micrologic P control unit. backed by incomparable security Protection functions are separate from the measurement functions and are managed by an ASIC electronic component. This independence guarantees immunity from conducted or radiated disturbances and ensures a high degree of reliability. A patented double setting system for protection functions establishes: * a maximum threshold set using the control-unit dials; * fine adjustments via the keypad or remotely. The fine adjustments for thresholds (to within one ampere) and tripping delays (to within a fraction of a second) are displayed directly on the screen. The control unit cover can be lead-sealed to prevent uncontrolled access to the dials and protect the settings. 6

Protection thresholds and delays are set using the adjustment dials. The selected values are momentarily displayed in amperes and in seconds. Setting accuracy may be enhanced by limiting the setting range using a different long-time rating plug. Overload protection True rms long-time protection. Thermal memory: thermal image before and after tripping. Short-circuit protection Short-time (rms) and instantaneous protection. Selection of I 2 t type (ON or OFF) for short-time delay. Earth fault protection Residual or source ground return. Selection of I 2 t type (ON or OFF) for delay. Residual earth-leakage protection (Vigi). Operation without an external power supply. d Protected against nuisance tripping. k DC-component withstand class A up to 10 A. Neutral protection On three-pole circuit breakers, neutral protection is not possible. On four-pole circuit breakers, neutral protection may be set using a three-position switch: neutral unprotected (4P 3t), neutral protection at 0.5 In (4P 3t + N/2), neutral protection at In (4P 4t). Zone selective interlocking (ZSI) A ZSI terminal block may be used to interconnect a number of control units to provide total discrimination for short-time and earth-fault protection, without a delay before tripping. menu Ammeter measurements... Micrologic A control units measure the true rms value of currents. A digital LCD screen continuously displays the most heavily loaded phase (Imax) or displays the I1, I2, I3, IN, Ig, I n, stored-current (maximeter) and setting values by successively pressing the navigation button. The optional external power supply makes it possible to display currents < 20% In.

35 Functions and characteristics Control units Micrologic P power E46017 Micrologic P control units include all the functions offered by Micrologic A.

Double setting Within the range determined by the adjustment dial, fine adjustment of thresholds (to within one ampere) and time delays (to within one second) is possible on the keypad or remotely using the COM option. IDMTL setting Coordination with fuse-type or medium-voltage protection systems is optimised by adjusting the slope of the overload-protection curve. This setting also ensures better operation of this protection function with certain loads. Neutral protection On three-pole circuit breakers, neutral protection may be set using the keypad or remotely using the COM option, to one of four positions: neutral unprotected (4P 3t), neutral protection at 0.5 In (4P 3t + N/2), neutral protection at In (4P 4t) and neutral protection at 2 In (4P 3t + 2N). Neutral protection at 2 In is used when the neutral conductor is twice the size of the phase conductors (major load imbalance, high level of third order harmonics). On four-pole circuit breakers, neutral protection may be set using a three-position switch or the keypad: neutral unprotected (4P 3t), neutral protection at 0.5 In (4P 3t + N/2), neutral protection at In (4P 4t). Neutral protection produces no effect if the long-time curve is set to one of the IDMTL protection settings. Programmable alarms and other protection... Depending on the thresholds and time delays set using the keypad or remotely using the COM option, the Micrologic P control unit monitors currents and voltage, power, frequency and the phase sequence. Each threshold overrun is signalled remotely via the COM option. Each threshold overrun may be combined with tripping (protection) or an indication carried out by an optional M2C or M6C programmable contact (alarm), or both (protection and alarm). Load shedding and reconnection... Load shedding and reconnection parameters may be set according to the power or the current flowing through the circuit breaker. Load shedding is carried out by a supervisor via the COM option or by an M2C or M6C programmable contact. Measurements... The Micrologic P control unit calculates in real time all the electrical values (V, A, W, VAR, VA, Wh, VARh, VAh, Hz), power factors and crest factors. The Micrologic P control unit also calculates demand current and demand power over an adjustable time period. Each measurement is associated with a minimeter and a maximeter. In the event of tripping on a fault, the interrupted current is stored. The optional external power supply makes it possible to display the value with the circuit breaker open or not supplied. Histories and maintenance indicators... The last ten trips and alarms are recorded in two separate history files. Maintenance indications (contact wear, operation cycles, etc.) are recorded for local access. Indication option via programmable contacts The M2C (two contacts) and M6C (six contacts) auxiliary contacts may be used to signal threshold overruns or status changes. They can be programmed using the keypad on the Micrologic P control unit or remotely using the COM option. Communication option (COM) The communication option may be used to: c remotely read and set parameters for the protection functions c transmit all the calculated indicators and measurements c signal the causes of tripping and alarms c consult the history files and the maintenance-indicator register. An event log and a maintenance register, stored in control-unit memory but not available locally, may be accessed in addition via the COM option. Note. Micrologic P control units come with a non-transparent lead-seal cover as standard. 20

The information made available depends on the type of Micrologic control unit (A, P or H) and on the type of communication bus (Digipact or Modbus). Switch-disconnectors may be connected exclusively to the Digipact communication bus. Communication bus Digipact The Digipact bus is the internal bus of the low-voltage switchboard in which the Digipact communicating devices are installed ( with Digipact COM, PM150, SC150, UA150, etc.). This bus must be equipped with a DC150 data concentrator (see the Powerlogic System catalogue). Addresses Addressing is carried out by the DC150 data concentrator. Number of devices The maximum number of devices that may be connected to the Digipact bus is calculated in terms of communication points. These points correspond to the amount of traffic the bus can handle. The total number of points for the various devices connected to a single bus must not exceed 100. If the required devices represent more than 100 points, add a second Digipact internal bus. Communicating device Number of points DC150 data concentrator 4 Micrologic + Digipact COM 4 PM150 4 SC150 4 UA150 4 Length of bus The maximum recommended length for the Digipact internal bus is 200 meters. Bus power source Power is supplied by the DC150 data concentrator (24 V).. 30

46 Modbus The Modbus RS485 (JBus) system is an open bus on which communicating Modbus devices ( with Modbus COM, PM300, Sepam, Vigilohm, etc.) are installed. All types of PLCs and microcomputers may be connected to the bus. Addresses The software layer of the Modbus protocol can manage up to 255 addresses (1 to 255). The device communication module comprises three addresses linked to: b circuit-breaker manager; b measurement manager; b protection manager. The craddle communication module comprises one address linked to: b the craddle manager. The division of the system into four managers secures data exchange with the supervision system and the circuit-breaker actuators. The manager addresses are automatically derived from the circuit-breaker entered via the Micrologic control unit (the default address is 47). logic Circuit-breaker manager (1 to + 50 Craddle manager (51 to Measurement managers (201 to Protection manager (101 to 147) Number of devices The maximum number of devices that may be connected to the Modbus bus depends on the type of device ( with Modbus COM, PM300, Sepam, Vigilohm, etc.), the baud rate (19200 is recommended), the volume of data exchanged and the desired response time. The RS485 physical layer offers up to 32 connection points on the bus (1 master, 31 slaves). A fixed device requires only one connection point (communication module on the device). A drawout device uses two connection points (communication modules on the device and on the craddle). The number must never exceed 31 fixed devices or 15 drawout devices. Length of bus The maximum recommended length for the Modbus bus is 1200 meters. Bus power source A 24 V DC power supply is required (less than 20% ripple, insulation class II). Communication interface The Modbus bus may be connected to the central processing device in any of three manners: b direct link to a PLC. The communication interface is not required if the PLC is equipped with a Modbus port; b direct link to a computer. The Modbus (RS485) / Serial port (RS232) communication interface is required; b connection to a TCP/IP (Ethernet) network. The Modbus (RS485) / TCP/IP (Ethernet) communication interface is required. Software To make use of the information provided by the communicating devices, software with a Modbus driver must be used. Micrologic utilities This is a set of Modbus drivers that may be used with a PC to: b display the variables (I, U, P, E, etc.) with the DDS (Data Display Software) application; b read/write the settings with the RSS (Remote Setting Software) application; b remotely control (ON / OFF) the device with the CSS (Control Command Software) application. These softwares are available upon request. SMS (System Manager Software) SMS is a software to monitor LV and/or MV electrical energy.

61 Functions and characteristics Source-changeover systems Presentation Remote-operated source-changeover systems This is the most commonly employed system. No intervention by human operators is required. The switch from the normal to the replacement source is controlled electrically. A remote-operated source-changeover system is made up of two or three circuit breakers or switch-disconnectors linked by an electrical interlocking system implemented in a number of manners. Device control is backed up by a mechanical interlocking system that protects against the consequences of an electrical malfunction and inhibits incorrect manual operation Service sector: c hospital operating rooms c safety systems for tall buildings c computer rooms (banks, insurance companies, etc.) c lighting systems in shopping centres. Automatic source-changeover systems When a remote-operated source-changeover system is combined with an automatic controller, the sources can be controlled automatically according to a number of programmed operating modes. This solution provides optimal energy management: c switching to a replacement source depending on any external conditions; c management of power sources; c regulation; c emergency source replacement, etc. A communications function for dialogue with a supervisor is available for the automatic controller. Industry: c assembly lines c propulsion systems on ships c essential auxiliaries in thermal power stations. IMG0021 Infrastructure: c port and railway installations c runway lighting systems c control systems for military installations. 46

62 Mechanical interlocking Electrical interlocking of two or three devices is used to create a remoteoperated source-changeover system. A basic mechanical interlocking system enhances the reliability of system operation. To ensure a continuous supply of power, certain electrical installations are connected to two power sources: c a normal source N; c a replacement source R which supplies the installation when source N is not available. A source-changeover system switches between the two sources. The system may include an automatic controller which manages switching according to external conditions. A source-changeover system may comprise two or three circuit breakers or switch-disconnectors Interlocking of two devices using connecting rods The two devices must be stack mounted. This function requires: c an adaptation fixture on the right side of each device; c a set of connecting rods with no-slip adjustments. The complete interlock kit is supplied for assembly by the customer. Maximum vertical distance between the fixing planes: 900 mm Combinations of Normal and Replacement devices NT and NW devices may not be used together in a source-changeover system. The two devices must both be fixed devices or drawout devices to maintain correct alignment of the mechanisms. Interlocking of two or three devices using cables Using cables, the devices may be stack mounted or installed side-by-side. Interlocking of two devices ( NT or NW) This function requires: c an adaptation fixture on the right side of each device; c a set of cables with no-slip adjustments. Maximum distance between the fixing planes (vertical or horizontal): 2000 mm Interlocking of three devices (only NW) This function requires: c an adaptation fixture (different for each type of interlocking) on the right side of each device; c two or three sets of cables with no-slip adjustments. Maximum distance between the fixing planes (vertical or horizontal): 1000 mm Installation The complete interlock kit is supplied for assembly by the customer. Combinations of Normal and Replacement devices All combinations of NT and NW devices may be used together in a sourcechangeover system. Interlocked devices may be fixed or drawout, three or four pole, with different ratings and sizes. 47

63 Functions and characteristics Source-changeover systems Electrical interlocking Electrical interlocking is used with the mechanical interlocking system. It controls switching between sources. An automatic controller may be added to take into account information from the distribution system. Electrical interlocking requires an electrical control device. This function can be implemented in one of two ways: c using the IVE electrical interlocking unit c by an electrician using the electrical systems presented in the diagrams in the Source-changeover systems section of this catalogue. Characteristics of the IVE unit c external connection terminal block: v inputs: control of devices v outputs: status of the SDE contacts on the Normal and Replacement devices. c connector to the two Normal and Replacement devices: v inputs: - status of the OF contacts on each device (ON or OFF) - status of the SDE contacts on the Normal and Replacement devices v outputs: power supply for motor mechanisms. c control voltage: v 24 to 250 V DC v 48 to 415 V 50/60 Hz v 440 V 60 Hz. The control voltage for the IVE electrical interlocking unit must be identical to that of the operating mechanism. Necessary equipment Each device must be equipped with: c a remote-operation system made up of: v MCH gear motor v MX or MN opening release v XF closing release v PF ready to close contact c an available OF contact c a CE connected-position carriage switch on drawout devices.

(5) time setting is manual and can be carried out automatically by the supervisor via the communications bus. The communications bus requires its own 24 V DC power source (E1, E2). This source is not the same as the 24 V DC external power-supply module (F1-, F2+). In case of using the 24 VDC external power supply (AD module), maximum cable length between 24 VDC (G1, G2) and the control unit (F1-, F2+) must not exceed 10 meters. The BAT battery module, mounted in series upstream of the AD module, ensures an uninterrupted supply of power if the AD module power supply fails. The voltage measurement inputs are standard equipment on the downstream connectors of the circuit breaker. External connections are possible using the PTE external voltage measurement input option. With this option, the internal voltage measurement inputs are disconnected and terminals VN, V1 and V2 are connected only to the control unit (Micrologic P and H only). The PTE option is required for voltages less than 100 V and greater than 690 V (in which case a voltage transformer is compulsory). For three-pole devices, the system is supplied with terminal VN connected only to the control unit (Micrologic P and H). When the PTE option is implemented, the voltage measurement input must be protected against short-circuits. Installed as close as possible to the busbars, this protection function is ensured by a P25M circuit breaker (1 A rating) with an auxiliary contact (cat. no and 21117). This voltage measurement input is reserved exclusively for the control unit and must not ever be used to supply other circuits outside the switchboard. 86

If there is a signal from downstream, the circuit breaker remains closed for the full duration of its tripping delay. If there is no signal from downstream, the circuit breaker opens immediately, whatever the tripping-delay setting. Fault 1. Only circuit breaker A detects the fault. Because it receives no signal from downstream, it immediately opens in spite of its tripping delay set to 0.3. Fault 2. Circuit breakers A and B detect the fault.

120 Derating in switchboard Factors affecting switchboard design The temperature around the circuit breaker and its connections: This is used to define the type of circuit breaker to be used and its connection arrangement. Vents at the top and bottom of the cubicles: Vents considerably reduce the temperature inside the switchboard, but must be designed so as to respect the degree of protection provided by the enclosure. For weatherproof heavy-duty cubicles, a forced ventilation system may be required. The heat dissipated by the devices installed in the switchboard: This is the heat dissipated by the circuit breakers under normal conditions (service current). The size of the enclosure: This determines the volume for cooling calculations. Switchboard installation mode: Free-standing, against a wall, etc. Horizontal partitions: Partitions can obstruct air circulation within the enclosure. Basis of tables c switchboard dimensions c number of circuit-breakers installed c type of breaker connections c drawout versions c ambient temperature outside of the switchboard: Ta (IEC ).
