GROUND CURRENT SENSOR ground fault protection monitor or relay designed for industrial electrical systems. It is primarily used to detect ground fault currents in three-phase AC systems to prevent equipment damage - Device Type: Ground Fault Monitor / Relay.Current Rating: Adjustable or rated for 5 to 60 Amps.Compatible Sensors: Used in conjunction with a GFP Sensor (current transformer).Common Part Numbers:179C767G01: Standard ground fault monitor model.1256C13G01: Another variation of the 5-60A monitor for GFP sensors.Detection Features: Often includes a Time Delay setting (instant to 60 cycles) to avoid nuisance tripping.Physical Dimensions: Typically measures approximately \(10.5" \times 10.5" \times 1"\) with an inner window diameter for cables around \(8.25"\)
