DescriptionOverload relays

ZEV electronic overload relay for motor currents from 1 820 A

Technological advances require completely new approaches: the application ofnewly developed sensor systems and tripping units has made motor protectionconsiderably simpler and more economical. All Z overload relays provide thestandard functions: protection in the event of phase failure, overload, or currentimbalance. The innovative ZEV motor-protective system from Moeller can now doall these things and much more:

Even the most severe starting situations can be dealt with by the ZEV motor-protective system. The enhanced tripping classes (up to CLASS40) provide reliableprotection for motors with starting times of up to 40 seconds. Protection for anymotor starting situation can be optimally set by preselecting one of the eighttripping classes between 5 and 40 seconds. An earth fault is quickly detected by theexternal core-balance transformers. The integrated thermistor connection allowsthe relay to be upgraded to provide a full motor-protective system.

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 cause of the faultand enables rapid fault identification.Additional signal cables can be implemented via the freely configurable auxiliarycontacts 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

The multi-voltage module automatically adapts to different voltagesfrom 24 240 V, 50/60 Hz,and 24 240 V DC, thus enabling flexible application with all conventional controlvoltages.

Ring-type sensors enable the innovative ZEV motor protection system to be usedalso for small motors. With large motor currents and cable cross-sections, the sensorcables are simply wound round the incoming cable.A main current wiring system and complex cable matching for an additional deviceare no longer necessary, neither is the drilling of the mounting plate. Instead, thesensors are simply fastened with a Velcro fastener.This saves mounting time and expense. The volume of 58 times less thanconventional transformers enables the saving of valuable mounting space in thecontrol panel.

Switchgear and cable sizing correspond to the respective starting inertia (CLASS)

The switchgear is designed for CLASS 10 in normal and overload operation. To ensure that the switchgear (circuit-breaker and contactor) as well as the cables are notoverloaded with extended tripping times, they must be over-dimensioned accordingly. The rated operational current Ie for switchgear and cables can be calculated withthe following current factor while taking the tripping class into account:

These tripping characteristics are mean values of the spread at 20 C ambient temperature in a cold state. Tripping time depends on response current. When the devicesare at operational temperature the tripping time of the overload relay reduces to approx. 25 % of the read off value. Specific characteristics for each individual settingrange can be found in the manual onaPage 6/18
