15 3K, 3KE, 3LD Switch Disconnectors 3LD Main and EMERGENCY-STOP Switches up to 125 General data Design Construction of the contacts Each switch has three adjacent contact elements 1). fourth leading contact element for switching the N conductor, a continuous PE/ground terminal, an auxiliary switch (1 NO or 1 NC) can be fitted to each side of the switch. The auxiliary switches operate as leading contacts on opening. On opening, the NO contact opens before the main contacts, so that a contactor carries the switching capacity in the circuit and the maintenance or safety switch switches at zero current. On closing, the auxiliary switch switches later than or at the same time as the main contacts. Switch construction Construction of rotary operating mechanisms The rotary operating mechanisms of the switches for front or floor mounting are mounted on control cabinet doors, front panels or side panels with four-hole or center-hole mounting with a standard diameter of 22.5 mm and operated from the outside. In their Off position, they can be locked with up to three padlocks with a hasp thickness of 8 mm. Controls with defeatable doorcoupling rotary operating mechanism are available in addition. Switch position indicator: The switch position is clearly marked with direction arrows and an "O" for OFF and a "I" for ON at the front. Switches for front mounting: The switches for front mounting are connected directly to the rotary operating mechanism through the fixing screws or - in the case of center-hole mounting - a special-purpose coupling. Switches for floor mounting: The switches for floor mounting are snapped onto 35 mm standard mounting rails according to EN or screwmounted on mounting plates. The actuators are connected to the lower section of the switch through a door coupling, which can be released in its zero position, and a 300 mm long switch shaft. When the control cabinet door is open, the switch can be protected against inadvertent operation by removing the switch shaft from the lower section of the switch. The mounting depth can be adapted to individual requirements by adjusting the switch shaft length. Switches for distribution board mounting: The switches for distribution board mounting are suited for operation in switchboards and for switching inside control cabinets or distributors. They have cap and mounting dimensions to DIN and can be fitted under the same cover together with miniature circuit breakers. The selector knobs can be locked in their OFF position with up to 2 padlocks with a hasp thickness of 6 mm. Switches in molded-plastic enclosure: For surface mounting of individual main control and EMERGENCY-STOP switches, molded plastic-enclosed switches to degree of protection IP65 are used. The actuators can be locked in their OFF position with three padlocks with a hasp thickness of 8 mm. The molded-plastic enclosures each contain an N and/or a PE/ground terminal. 1) 16 versions have four contact elements; 3-pole changeover switches and 6-pole main control switches have six contact elements. 3LD TK5 switch for front mounting with rotary operating mechanism 3LD UK01 3-pole changeover switch for front mounting with selector knob 3LD TK5 switch for floor mounting with rotary operating mechanism and door coupling 3LD TB5 switch in molded-plastic enclosure 3LD TK1 switch for front mounting with selector knob 3LD VK53 6-pole switch for front mounting with rotary operating mechanism 3LD TK11 switch for distribution board mounting with selector knob 3LD TL13 switch for floor mounting with rotary operating mechanism and defeatable door coupling Siemens

36 3KL, 3KM, 3NJ6 Switch Disconnectors with Fuses 8UC Door-Coupling Rotary Operating Mechanisms For 3K switch disconnectors Overview NSE0_00350a max.5 -max.5 max.5 +max.5 max.5 max.5 Permissible radial eccentricity and axial tolerance compensation Switch position In order to ensure compliance with locking and interlocking conditions, the controls and operating mechanisms must be installed such that, with two-position switches the "0" position lies at 9 o'clock and the "I" position at 12 o'clock. 4 standard sizes of operating mechanisms are available: Size Rated torque 1) Shaft profile Masking plate Nm mm x mm mm x mm x 6 75 x x 8 75 x x 10 or 100 x x /55 2) 12 x x 100 1) Operating mechanisms tested with triple torque (VDE 0660 Part 107). They are therefore qualified for use in all controls, especially for disconnectors. 2) Operation with two hands. Design Operating mechanisms consist of a masking plate with handle including seal and fixing screws for door installation and of a shaft coupling, extension shaft (300 mm) and coupling driver to be mounted onto the switch shaft. Operating mechanisms for 3K/3KL/3KM switch disconnectors do not have a shaft coupling since the extension shaft is fitted directly into the switch. Extension shafts with a length of 600 mm are available. Masking plates are light-gray with black inscription, handles are ti-grey. For EMERGENCY-STOP switches, a yellow indicator plate with black inscription is mounted; the handles are red. The retractable locking device (light green basic) for padlocks is integrated in the handle. The door interlock on the rotary operating mechanisms is suitable for padlocks with shackle diameters of 4.5 mm to 8.5 mm (locks according to DIN 7465). Up to three locks with shackle diameter of 8.5 mm or up to five locks with shackle diameter of 6 mm can be fitted. Mounting instructions are included in the scope of supply. Operating instructions containing hints on activation or modification of interlocking conditions are available by quoting Order No. 8ZX1012-0UC60-11 or can be downloaded. The Internet address is: 8UC7 door-coupling rotary operating mechanisms are capable of taking up a radial eccentricity of max. 5 mm between the actuating shaft of the switching device and the operating mechanism. Supporting the extension shaft is recommended with greater tolerances. ±5 mm can be compensated in axial direction. The distance between the door hinge and the center of rotary operating mechanism must not be less than 100 mm NSE0_00352a 1 12 o'clock position 2 9 o'clock position Positions for two-position switches with 90 operating angle Non-interchangeability In order to ensure that, when installing switches and door-coupling operating mechanisms, all components - the actuating shaft, shaft coupling, extension shaft, coupling driver and doorcoupling operating mechanism - are assembled in the correct position with respect to one another, all the above-mentioned parts are provided with non-interchangeability features (groove and lug). For controls whose non-interchangeability groove is not at 3 o'clock in the "0" position or switches that can be installed at an angle of 90 to the left or right, the non-interchangeability groove can be repositioned. When the switch and the door coupling are fitted, the rivet in the shaft coupling or coupling driver is moved accordingly. ll doorcoupling rotary operating mechanisms listed in this catalog are supplied with the "0" position of the mechanism at 9 o'clock and the "I" position at 12 o'clock. This refers to controls to be installed in the normal mounting position. In operation and when performing maintenance, these non-interchangeability features preclude the risk of accidents caused by incorrect handling or incorrect switching operations.

37 3KL, 3KM, 3NJ6 Switch Disconnectors with Fuses 8UC Door-Coupling Rotary Operating Mechanisms For 3K switch disconnectors Handle ctuating shaft of the control Correlation between handle of rotary operating mechanism and actuating shaft Stops To prevent damage to smaller switches, an excessive manual operating torque can be absorbed by stops fitted on the inside of sizes 1 and 2 rotary operating mechanisms. These stops are supplied loose with the operating mechanisms and can be fitted as required after consulting the operating instructions. Stops are fitted at the factory to size 1 and 2 operating mechanisms with a 90 operating angle (exception: 3V. circuit breakers). Pull-out strength The pull-out strength of interlocked operating mechanisms, e. g. pulling off the shaft or destruction of the operating mechanism, amounts to 800 N when the pulling force acts directly onto the operating mechanism in direction of shaft. NSE0_00354 Function The basic (standard) versions of the rotary operating mechanisms comply with the following interlocking conditions: Operating mechanism and switch in "0" (OFF) position: The control cabinet door can be opened, the operating mechanism is uncoupled and the handle of the rotary operating mechanism engages. If padlocks are fitted with the control cabinet door closed and the actuator is set to "0", the operating mechanism (and switch) cannot be actuated and the door cannot be opened. Operating mechanism and switch in "I" (ON) position: The control cabinet door cannot be opened in this position. The interlocking mechanism can, however, be overridden by trained personnel (pressing of a concealed latch with a screwdriver or the like), thus making it possible to open the control cabinet door in the "I" position of the control for performing checks. The handle engages in the "I" setting with the door open. In the "I" position it is not possible to fit padlocks to lock the operating mechanisms. Other interlocking conditions If no door interlock is required, the user can remove the door interlocking plate of the rotary operating mechanism after consulting the operating instructions. If provision is to be made for fitting padlocks to the rotary operating mechanism in the "I" position as well, the user can easily achieve this after consulting the operating instructions by knocking out a lug. Such a measure must not, however, be implemented with EMERGENCY-STOP rotary operating mechanisms. If padlocks are fitted in the "I" position of the rotary operating mechanism, the mechanism cannot be actuated, the control cabinet door cannot be opened and the operating mechanism cannot be overridden in order to open the door. If necessary the rotary operating mechanisms can also be locked in the 90, 180 position etc. as well as in the "0" position. The measures previously listed in item 2 under "Other Interlocking Conditions" must be carried out by the user. In the case of rotary operating mechanisms for switches without "0" position, such as stepping switches without "0" position, the door interlocking plate is removed. Siemens

Version "" stands for "open-circuit principle", version "R" for closedcircuit principle" (see schematic circuit diagram on page 53). If a fuse is tripped, a green LED signal flashes (general fault) and the location of the failed fuse is indicated by a red LED. Using more than one device facilitates identification of the affected branch circuit. The EF monitor is automatically reset to the standby position once the faulty fuses are replaced. This state is indicated visually by the status display (green LED). The EF monitor is also suitable for operation in industrial networks badly afflicted by harmonics. Siemens

61 8US Busbar Systems General data Overview Design Function 8US busbar systems with 40 mm and 60 mm busbar center-tocenter spacing as well as flat copper profiles have now become Short-circuit strength firmly established on the world market. The permissible busbar temperature is a decisive factor when dimensioning the busbars. The busbar temperature is dependent on the current and the current distribution, on the busbar cross-section and the busbar surface, on the position of the busbars, convection and the ambient temperature. The values stated in the following table can only be considered as guide values because the conditions vary with each location. The values are based on uninterrupted current over the whole busbar length. The busbar runs prove most advantageous when the incoming supply is centrally located and the load is distributed symmetrically on both sides. 8US busbar systems are designed for horizontal mounting of the busbars. The short-circuit strength of the busbar system is dependent on the distance of the busbar supports and on the busbar cross-section. The short-circuit strength of the whole system is dependent on the short-circuit strength of the busbars and of the adapters with circuit breakers or switch disconnectors (see "Molded case circuit breakers (MCCB)" and "Switch disconnectors"). If one of these values is lower than the prospective short-circuit current at the place of installation, a current-limiting protective device has to be mounted upstream of the 8US busbar system. This may also be mounted as a feeder circuit breaker on the busbar system itself. Siemens
