The PGR-4700 series relay operates on solidly-grounded and resistance-grounded ac systems. This sensitive ground-fault relay provides exceptional low-level protection without the issues associated with high-sensitivity nuisance tripping. It detects very low-level leakage current on large circuits to avoid or significantly reduce equipment damage and injury to personnel. The leakages can be identified as they develop, and ground-faults can be detected before they become critical. The PGR-4700 is compatible with variable frequency drive applications. These ground-fault relays can be used for the protection of critical circuits in panel boards and switchboards, 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.
