Combination Ground Monitor & Fault Relay

This is a low voltage ground monitor / ground fault relay assembly combining the SMCModel 6314-023 ground monitor with an integral ground trip relay. The ground trip relay utilizes a breaker for tripping and indication similar to SMC Model C-3043-1. The relay will monitor change in ground wire resistance and ground fault current tripping the circuit breaker if resistance or ground currents increase to an unacceptable level providing assurance of safely grounded electrical equipment and protection to personnel. It monitors up to 4.5 ohms ground / pilot loop resistance and trips at 5 amperes ground fault current. It is adaptable for use with shunt trip or undervoltage devices. An onboard selector switch provides the flexibility to use virtually any existing ground fault current transformers. Its compact design allows the same mounting arrangements of other existing units.
