ZEV – The revolutionary motor-protective relay for motor currents from 1–820 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 motor-protective 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 and safe to operate:The LCD display guides the user through the setting menus and ensures straight-forward 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 05-06 and 07-08. They can each be assigned one of the following functions:

• Early warning of overload• Earth-fault• Thermistor tripping• Internal fault

Simple engineering:The multi-voltage module automatically adapts to different voltages from 24 – 240 V 50/60 Hz and 24 – 240 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.

Contactor selection based on starting duty (CLASS)

Contactors for normal and overload operation are designed to CLASS 10. 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:

ICLASS = ICLASS 10 = Ie ICLASS 15 = Ie 0.82 ICLASS 20 = Ie 0.71 ICLASS 25 = Ie 0.63 ICLASS 30 = Ie 0.58 ICLASS 35 = Ie 0.53 ICLASS 40 = Ie 0.5

Tripping units with built-in sensor

With ZEV-XSW-25 to ZEV-XSW-145 ring-type sensors, the motor supply leads are passed through the apertures, one phase at a time. For motor currents of less than 1 A, the motor supply leads have to be looped back through ZEV-XSW-25. The number of loops is governed by the rated motor current.

Tripping characteristics

These tripping characteristics show mean values of the tolerance range at 20 °C ambient temperature starting from cold. They show the tripping times in relation to the response current. At operational temperature, the tripping time of the overload relay

drops to approximately 25% of that shown. Specific characteristics for each individual setting range are available on request. These characteristics for ZE, Z00, Z1 and Z5, format 55 75, self-adhesive, correspond to the data in the PTB test report and are used both

for the correct selection of overload relays for EEx e motors and for documentation at the point of installation.

In the event of phase failure or an imbalance > 50 %, the ZEV trips out within 2 – 3 seconds.
