Overcurrent and ground protection SPAJ 141C provides optional short circuit and ground protection for radial distribution feeders in power systems with direct ground, resistance ground or impedance contact. The integrated protection relay includes an overcurrent protection unit and a ground protection unit with flexible tripping and signaling functions. Overcurrent and ground protection devices can also be used in other applications that require single-phase, two-phase or three-phase overcurrent protection and ground protection. Overcurrent and ground protection includes a circuit breaker failure protection unit.

The overcurrent and ground protection device SPAJ 141C is part of the distribution automation concept produced by ABB, which extends ABB’s solution for the measurement, control and management of power systems.
