ELRM44V30 115/230VAC

The ELRM44V-30 series Variable Earth Leakage Relay designed to monitor and detect true RMS earth fault currents in conjunction with a separate toroid. The LED bargraph provides constant indication of any leakage current. It has connection facility for remote "test" and "reset" push buttons or NO contacts. The toroid open circuit detection forces unit to trip (red LED flashes during this condition).

• Microprocessor controlled with internal monitoring (self-checking)
• Adjustable sensitivity (I∆n) and time delay (∆t) of 0 (instantaneous) to 10sec
• Separate "test" and "reset" push buttons
• 2 Relay outputs - Standard output (SO) and positive safety output (PSO)
• LED indication of supply status and fault condition after unit has tripped
