Features of the ASE GF-1 Ground Fault Protection Unit

The ASE GF-1 provides an inexpensive, easy to integrate answer for your GFPE requirements. The 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, anywhere from 15A to 60A. Then install the GF unit between your load center branch circuit and the sensor/controller and heat cable. Your overload breaker protects the wiring. Our GF unit provides the Ground Fault Protection.

The unit is housed in a rugged, NEMA 4X/IP65 rated enclosure, suitable for mounting indoors or outdoors. The enclosure features a gasket-sealed front access door for easy testing and reset. All internal electronic components are specified for -40degC to +60degC operation. The enclosure is simple to surface mount either near the load center or near the snow melt system, whichever is preferred. Numerous knockout locations on the enclosure provide flexibility for installation and wiring. The enclosure base can accommodate standard 1/2" and 3/4" conduit hubs. Four mounting holes "outside" the enclosure gasket make mounting a breeze while assuring weathertight performance.

Application Information

The National Electrical Code and Canadian Electrical Code both require it. And you know you need it to be compliant. But a true 30mA trip point GFPE breaker can be hard to find. And, if you DO find one for your specific load center, prepare for special ordering, long lead times, and high costs! If you are working on an older home a GFPE breaker may not be available. And substituting a GFCI may help protect...until the high sensitivity causes a false trip and damage occurs from a non-functioning snow melt system.
