Ground Fault Protection Unit - Required By UL

Ground Fault Protection Unit

Provides an affordable solution for your GFPE requirements. Each ground fault unit affords GFPE protection for one or multiple circuits up to 32 amp per circuit. Our unique design allows installation of your own standard, off-the-shelf overload breaker into the customer load center. Size the breaker and wiring for your system, as required for the amperage selected. Then install the ground fault unit between your load center branch circuit and the sensor/controller and heat trace cable. Your overload breaker protects the wiring, and our ground fault unit provides the ground fault protection.

NEMA 4X rated enclosure, can be mounted indoors or outdoors. Enclosure features a gasket-sealed front access door for easy testing and reset. All internal electronic components are spec'ed for -40°C to +60°C operation. The enclosure is simple to surface mount either near the load center or near the snow melt system, whichever is preferred.

Can be used with contactor panels, switches, and/or any system up to 32A. Since the overload protection is provided by the load center breaker only two ground fault models are required to cover the full range of 15A to 30A, one or multiple circuits. This helps keep stocking costs low, but also allows including ground fault protection with kitted systems without the requirement of identifying the customer's load center type, and researching if a combined overload/GFPE breaker is available.
