SPAJ140C-AA
The combined overcurrent and earth-fault relay SPAJ 140 C is intended to be used for the selective short-circuit and earth-fault protection of radial feeders in solidly earthed, resistanc earthed or impedance earthed power systems.
The integrated protection relay includes a phase overcurrent unit and an earth-fault unit with flexible tripping and signalling facilities. The overcurrent and earth-fault relays can also be
used inother applications requiring single-, twoor three-phase overcurrent protection and nondirectional earth-fault protection. The combined overcurrent and earth-fault relay also features circuit breaker failure protection.
