Open Off Open Off Closed OnPower Supply NotesAll low-current ground-fault sensors are sensitive devices thatrequire reasonable care in system design to avoid false trips causedby high electrical noise levels. Keep in mind that the best way toreduce noise in a system is to suppress it at its source.• Keep the sensor power isolated from noisy circuits.• Do not power the sensor with the same circuit that switches con-tactors or other high current inductive loads.System GroundingGood design practice and code require that all AC power systemsbe grounded. The EGFL Series sensors are designed to work ongrounded AC power systems. They may not operate properly onungrounded systems.SpecificationsSpecification ValuePower Supply 120 VAC (Operates from 66-132 V, 50-400 27 Hz)24 VAC/DC (Operates from 19.2-28.8 V)Voltage Range Up to 1,500 VAC (Monitored Circuit)Power Consumption 2.5 WOutput SPDT Form C Electromechanical Relay with Auto Reset uponremoval of fault conditionOutput Rating 1.0 A @ 120 VAC2.0 A @ 30 VDCResponse Time 15 ms: At 500% Over Setpoint60 ms: At 50% Over Setpoint200 ms: At 5% Over SetpointSetpoint Range Adjustable Setpoints: 5, 10, 30 mA (by Jumper)Frequency Range 50-400 Hz (Monitored Circuit)Housing UL94V-0 Flammability RatedDimensions Case: 4.25 in.
