Numerical Over Current Relay

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.
