Being a client-centric organization, we are engaged in manufacturing, supplying, exporting and trading Numerical Over Current Relay. Based Over Current Relay (OCR) with Earth Fault Relay (EFR), these relays are extensively used for selective over current. Apart from this, applicable in substations and industrial networks, these relays are widely used for earth fault protection of radial feeders in impedance earthed power systems.

Definite time curve for both Phase & Earth along with optional user defined curve
Low AC burden
Reliable auxiliary supply of wide range input of 18-85 or 85-275 volts AC or DC
Non-Volatile memory for data retention and retrieval in the event of power failure
Unique combination of 505150N51N in a single gadget
Consistent repeat accuracy
High Drop-offPick-up ratio
Poly carbonate front cover with external reset switch
