6 06/00 Overload Relays, Motor-Protective Relays Description ZEV The revolutionary motor-protective relay for motor currents from 80 A Technological advances require completely new approaches: the application of newly developed sensor systems and tripping units has made motor protection considerably simpler and more economical. All Z overload relays provide the standard functions: protection in the event of phase failure, overload, or current imbalance. The innovative ZEV motor-protective system from Moeller can now do all these things and much more: Severe starting conditions: Even the most severe starting situations can be dealt with by the ZEV motorprotective system. The enhanced tripping classes (up to Class 40) provide reliable protection for motors with starting times of up to 40 seconds. Protection for any motor starting situation can be optimally set by preselecting one of the eight tripping classes between 5 and 40. An earth fault is quickly detected by the external core-balance transformers. The integrated thermistor connection allows the relay to be upgraded to provide a full motor-protective system. Simple engineering: The multi-voltage module automatically adapts to different voltages from 4 40 V 50/60 Hz and 4 40 V DC, thus enabling flexible application with all conventional control voltages. Simple and space-saving mounting: Ring-type sensors enable the innovative ZEV overload relays to be used even for small motors. With high motor currents and large cable sizes, the sensor cables are simply laid around the supply cables. There is no need for main circuit wiring with complex cable matching to another unit, nor for drilling a mounting plate. Instead, the sensor is simply affixed using a Velcro fastening, saving installation time and expense. The volume of the transformer is reduced by up to 58 times in comparison with conventional transformers, saving valuable space in the control panel. Simple and safe to operate: The LCD display guides the user through the setting menus and ensures straightforward operation. In the event of a fault, the display shows the origin of the fault and enables rapid fault identification. Additional signals can be implemented via the freely configurable auxiliary contacts and They can each be assigned one of the following functions: Early warning of overload Earth-fault Thermistor tripping Internal fault

The maximum rated operational current of the contactor must be reduced depending on the CLASS setting on the ZEV so that the contactors are not thermally overloaded if the tripping times are relatively long. The rated operational current Ie of the contactors can be calculated using the following derating factors: I CLASS = I CLASS 0 = I e I CLASS 5 = I e 0.8 I CLASS 0 = I e 0.7 I CLASS 5 = I e 0.63 I CLASS 30 = I e 0.58 I CLASS 35 = I e 0.53 I CLASS 40 = I e 0.5 Tripping units with built-in sensor With ZEV-XSW-5 to ZEV-XSW-45 ring-type sensors, the motor supply leads are passed through the apertures, one phase at a time. For motor currents of less than A, the motor supply leads have to be looped back through ZEV-XSW-5. The number of loops is governed by the rated motor current. Number of loops 4 3 Rated motor current I N [A] Setting current on the relay I E [A] between the minimum and maximum value The setting current I E for the unit is calculated as: I E = n I N
