Ground fault protection panels, types GPD and GPFJ, were developed to provide sensitive protection against low value ground fault currents. Multiple models operate up to 600V and are equipped with non automatic breaker of either 100 or to 225 amperios. Trip level settings range from 5 to 50mA.
There are two basic panels: 100A (GPD/GPAD) and 225A (GPFJ/GPAFJ), both equipped with a non-automatic breaker*, a thermo magnetic breaker is available as an additional option, with the indicated current capacities. Types GPD and GPFJ are designed for grounded or resistance grounded systems while types GPAD and GPAFJ are designed for ungrounded systems.
* For automatic breakers please consult I-Gard Sales
The GPD, GPAD, GPFJ AND GPAFJ panels contain a ground fault detector having a non-adjustable pick-up setting from 5 to 50mA nominal, a non-automatic circuit interrupter, 2 in. diameter current sensor and a 25VA control transformer, which provides a 120V AC tripping supply to the interrupter shunt trip.
