Model CRP 22 Overload Relay Up to 500 Motor FLA

Product #:	CRP22-3S-22
Brand:	Cerus Industrial
Description:	Factory Stock 4.4 to 22 Amp range when used without Current Transformers. For over 22 amps, use three current transformers with 5 amp secondaries, set Trip Amps at 5, select current transformers so that the motor rated FLA is close to mid-range of the primary amps. Order a Current Transformer Motor Protection: Preventing the Burn-out Models CDP and CRP are current sensing devices. Loss of phase will give a positive trip with a complete loss of phase current. Other voltage sensing devices will always see a voltage on all three legs for the reason that the unpowered motor leg will act as a transformer and therefore give an output voltage to the sensor. The sensor will then see three voltages on the motor and will need to be finely tuned. Adjustable Trip Amps Solid-state Microprocessor Based Class 1 to 30 infinitely selectable via trip time setting: 0 to 30 Seconds, set time is the trip time at six times the set current. Control Power Required: 100 to 260 VAC, 50/60 Hz, 1 PH Operational Temperature: -25 to +70 degrees C Three Phase Screw or DIN rail mount. Screw Terminals Protections: Phase current unbalance Phase loss/phase failure Stall Protection Phase current unbalance: trips within 5 seconds when the phase current unbalance exceeds 50%. Phase loss/phase failure: trips within 3 seconds when phase current is 70% unbalanced. Stall Protection: Trips at 170% of full load amps at 3 seconds. LED indication of faults for over current, phase failure. Units for single phase and units with current tunnels rather than screw termnals are also available. 18 Month Warranty Shipping by ground UPS is included in the price shown.
