Sensitive Ground Fault Relay Touch Screen

The legacy SFG-25 display has been innovated with a new state of the art microprocessor control and provides additional features to be used with the traditional SFG-25.


The SGF-25 Relay is used typically for critical 2300 to 4160 volt medium voltage applications where very sensitive, high accuracy ground current protection with a high degree of nuisance tripping immunity is very important. The new display is a plug and play replacement for the legacy unit both mechanically and electrically.
