Ground Fault Relays

GFR4000 Ground Fault Monitor

• The GFR4000 continuous ground fault monitor relay is specifically designed to provide complete motor protection without the problems associated with high sensitivity nuisance tripping. The GFR 4000 is unique because it has predictive as well as protective capabilities. The unit operates continuously in one of two modes, either on-line or off-line. The GFR4000 has metering output signals for use with a remote meter or PLC so that ground faults may be detected at an early stage.

RCD300M2 Ground Fault Relay

• The RCD300M2 residual current relay has been designed to provide sensitive ground fault protection without the problems associated with high sensitivity nuisance tripping. The RCD300M2 operates continuously and has the unique feature of a meter or interface with a PLC. This metering output signal gives the RCD300M2 both protective and predictive capabilities. By using the metering output, leakages can be seen as they occur and ground faults may be detected at an early stage before they become critical.
