4 ROBUST MOUNTING TO CONTACTOR 27A 55A Electronic overload relays CEP7 comprehensive motor protection Sprecher + Schuh have introduced their new CEP7, second generation electronic overload protection relays. The new CEP7 overloads incorporate a greater use of sophisticated electronic control and monitoring. With recent advances in micro electronic technology and the introduction of the ASIC chip set, it has become possible to improve on and add new features to the popular CEP7 range. The CEP7 second generation overload now incorporates greater accuracy and versatility whilst providing increased overall protection. The new CEP7 incorporates the following improved features: A wider settable current range (5:) Adjustable class trip settings (, 5, 2 and 3) (EE version) Field installable side mount modules (EE version) An extremely low power consumption Robust mounting to contactor Dip switch settings (EE version) 9A 8A Range overview CEP7-ED basic model The CEP 7-ED is the standard or base model version. The ED model is available in the current range of. - 45A, incorporates a fixed trip class of, and is suited to 3 phase operation. A manual reset function, visible trip indicator and test / reset button are also included. CEP7-EE enhanced model The enhanced CEP7-EE variant covers an operating range of. - 8A with adjustable trip class settings of, 5, 2 and 3 (via dip switch selection). The EE model can be further enhanced by the addition of side mounted plug-in modules. CEP7-E_P pass through model For current ranges - 27A a version is available that mounts separate from the contactor. The motor wires pass through CT openings. Superior phase failure protection Onboard electronics constantly monitors all motor phases. If the ASIC chip set senses that one or more of the phases is missing during a steady state operation of a fully loaded motor, it will trip in 3 seconds. If a single phase condition is present during starting, the CEP7 will trip within 8 seconds (for a motor loading of > 8 %). These trip times are significantly faster then conventional bimetal overloads. In addition, the CEP7 relay detects a 5 % phase imbalance in the same way as a phase loss. Rated up to V AC Complies to IEC-6997 for nominal operation voltage of volts. 27A 4

5 Modular in design, clever in application The new CEP7-EE overloads now offer a formidable range of smart add on modules. These small side mounted plug-in modules extend the CEP7 capability to something more potent in terms of motor protection. Communication modules are also available.

9 CEP7-E_P Pass Through Electronic Overload Relays The CEP7-E_P versions provide additional application flexibility and are designed to be mounted separately from the contactor. The motor wires are simply passed through the CT openings in the device and straight to the contactor which reduces the number of connection points. This makes them ideal in retrofit applications and when used with contactors other than CA7 or where space is restricted. The P version can be fitted directly onto DIN rail to speed up assembly. The EE_P version can also accept any of the side mount accessories including the communication modules; DeviceNet TM, Profibus or Ethernet / IP.

11 CEP7-CBCT Core Balance Transformers for CEP7-EGF/EGJ Ground fault current is sensed by passing all lines carrying current to and from a motor through the window of a special core balance current transformer often called a toroid / ground fault sensor. If all the current to the motor returns through the lines in the toroid, no significant current will be induced in the toroid secondary. If, however, ground fault current returns via a path external to the toroid, such as via the conduit walls, a current will be induced in the toroid secondary. This current will be sensed and amplified by solid state circuits. If the ground fault current is larger than the selected ground fault trip level of the overload relay, the overload relay will trip.

Under no conditions should a ground fault trip take longer than 3 seconds 22

23 Power cable installation All power cables, including the neutral when used, must pass through the sensor window. The equipment ground conductor (the conductor used to carry the non-current carrying metal parts of equipment) must not pass through the sensor window. 2 The power cables, going through the sensor window, must be straight, tightly bundled, centred in the window, and perpendicular to the sensor for a length equal to or greater than six times the cable bundle diameter (including insulation) from the sensor (see Figure ). 3 All other conductors with available fault currents in excess of, A should be placed a distance equal to or greater than six times the cable bundle diameter (including insulation) from the sensor (see Figure 2). 4 The power cables of the branch circuit, to be protected by the overload relay, must not be grounded on the load side of the ground fault sensor. 5 If the power cables are enclosed in a conducting jacket, the jacket must be grounded on the line side of the sensor. The jacket must not pass through the sensor window, but must be cut at the window and joined with a conductor that passes outside the sensor window. 6 The power system must be solidly grounded or grounded through an impedance at the source, as long as the impedance allows for a magnitude of current to flow that is within the operational range of the overload relay. CEP7 overload relay with CEP7-EGF or CEP7-EGJ (CEP7-EE) Figure Figure 2 Attention: To prevent electrical shock, disconnect from power source before installing or servicing. Install in a suitable enclosure, keep free from contaminants. Do not apply power to a system with power cables going through the sensor unless the sensor is connected to the overload relay. Operation without a low impedence connection to the secondary windings may result in damage to the sensor. 23

24 Locating phase conductors in the sensor window Firmly secure the conductors in the centre of the sensor window so that they cannot be moved accidentally or under fault conditions Maintain as large a distance as possible between the bundled conductors and the wall of the sensor window For applications having one cable per phase, arrange the conductors per Figure A For applications having two cables per phase, arrange the conductors per Figure B. A spacer, having the same diameter as the conductors being used, should be used to separate the phase conductors Single cable per phase Two cables per phase A B C C B A A B C spacer Figure A Figure B Attention: The ground fault protection system is intended for equipment use only. This system is not a ground fault circuit interrupter for personnel protection. An ideal core-balanced ground fault toroid responds only to the sum of the currents flowing through the sensor window, however, an actual core balanced transformer may saturate if the phase currents are too large. This results in ground fault sensor output even if the sum of the phase currents is zero. Saturation can be minimised by choosing a ground fault sensor with adequate core size and symmetrically locating the phase conductors in the centre of the sensor window as shown above. 24
