POWR-GARD Protection Relays, Monitors & Systems Ground-Fault Protection Solidly Grounded System (PGR 4000 Family) PGR-4700 SERIES (RCD300M2) Sensitive Ground-Fault Relay Description The PGR-4700 Sensitive Ground-Fault Relay provides sensitive ground-fault protection without nuisance tripping. It detects very low-level leakage current on large circuits to avoid or signicantly reduce equipment damage. The leakages can be identied as they develop and ground faults can be detected before they become critical. Applications Ground-fault relays can be used for the protection of critical circuits in panel boards and switch boards, OEM power distribution panels and custom controls. They are typically used in critical load applications with costly downtime and hazards, such as high humidity, water, dust, chemicals, and vibration.
