Sensitive Ground-Fault Relay
The PGR-4700 sensitive ground-fault relay provides sensitive ground-fault protection without the problems associated with high-sensitivity nuisance tripping. It detects very lowlevel leakage current on large circuits to avoid or significantly reduce equipment damage and injury to personnel. The leakages can be identified as they occur and ground-faults can be detected before they become critical.
