Description:
Two of three phase motor currents are monitored by current transformers. The CTs form integral part of the relay and external CTs are required for currents above 60AMPS. Internal solid state circuitry compares the actual motor current with the preset point, due to overload or single phasing, red LED illuminates and after the elapse of the preset delay time, SPDT relay switches contact. The red LED remains illuminated, indicating an overload trip has occurred.
After the elapse of preset RESET delay time (Maximum 120 sec). It resets automatically immediate reset with of RESET button or remote electrical reset by interrupting control power is possible. The starting delay and trip delay times are simultaneously set with single O-time Knob and these timing functions are not independent. TEST button provides means of testing the operation and integrity of the device with or without motor running. The actual load current can be determined with visual aid of LED (no Ammeter required). Simply adjust the load knob slowly anti-clockwise until red LED flickers. The flickering red LED indicates 100% of actual motor current.
