The ground trip relay is designed for use with 120 VAC undervoltage or shunt trip breakers on circuits limited to 25 amps or less ground fault current. It is factory adjusted to trip at less than 6 amps ground fault through a current transformer. This relay uses a breaker for tripping and indication. When a ground fault current occurs the breaker trips and must be manually reset. A resistor in series with the breaker undervoltage to limit current on a ground fault is not required.

C-3043-3
The ground trip relay is designed for use across a Neutral Grounding Resistor (NGR), for potential back-up. It incorporates a adjustable time delay from 0-5 seconds. It connects directly across NGR. See notes on schematic diagram.This relay uses a breaker for tripping and indication. When a ground fault occurs the breaker trips and must be manually reset.
