The Chromalox STAR-GF series wall mounted ground fault detectors are designed to monitor
for any gradual changes in the insulation level due to humidity or mechanical damage as they
develop and will de-energize the load to prevent arcing type faults, preventing premature element
failure and potential fire damage. The detector consists of a ground fault sensor, control circuit
transformer, magnetic contactor and an on off toggle switch with rubber boot, completely prewired
ina NEMA 4 enclosure.
