Electronic overload relays

CEP 7 comprehensive motor protectionSprecher + Schuh have introduced their new CEP 7, second generation electronic overload protection relays. The new CEP 7 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 CEP 7 range. The CEP 7 second generation overload now incorporates greater accuracy and versatility whilst providing increased overall protection.

The new CEP 7 incorporates the following improved features:

• Awidersettablecurrentrange(5:1)

• Adjustableclasstripsettings(10,15,20and30)(EEversion)

• Fieldinstallablesidemountmodules(EEversion)

• Anextremelylowpowerconsumptionof150mW

• Robustmountingtocontactor.

Range overview

CEP 7-ED1 basic model

The CEP 7-ED1 is the standard or base model version. The ED1 model is available in the currentrangeof0.1-45A,incorporatesafixedtripclassof10,andissuitedto3phaseoperation. A manual reset function, visible trip indicator and test / reset button are also included.

CEP 7-EE enhanced model

TheenhancedCEP7-EEvariantcoversanoperatingrangeof0.1-800Awithadjustabletripclasssettingsof10,15,20and30(viadipswitchselection).TheEEmodelcanbefurther enhanced by the addition of side mounted plug-in modules.

CEP 7-E_P pass through model

Forcurrentranges1-27Aaversionisavailablethatmountsseparatefromthecontactor.The motor wires pass through CT openings.

Superior phase failure protectionOnboard 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,theCEP7willtripwithin8seconds(foramotorloadingof>80%).Thesetriptimesaresignificantlyfasterthenconventionalbimetaloverloads.Inaddition,theCEP7relaydetectsa50%phaseimbalanceinthesamewayasaphaseloss.

Rated up to 1000 VACComplies to IEC-60997 for nominal operation voltage of 1000 volts.

The circuit inhibits the protection feature during the motor start period and arms the protection function after the inrush current falls to motor rated current. This allows the motor to start and run, avoiding nuisance tripping during the inrush period.
