Ground-Fault Protection – Solidly Grounded System (PGr 4000 Family)
12
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 significantly reduce equipment damage. The
leakages can be identified 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.
