ELRM44V-30 Earth Leakage Relay is used in conjunction with an external Core Balance Current Transformer (CBCT) and will detect residual sinusoidal alternating and pulsating direct currents. An adjustable trip level and time delay allows the product to be set according to the type of installation to be protected. When the level of leakage current being monitored exceeds the set trip level, the unit will trip. Typically, the product is used in conjunction with an external switching device (i.e. contactor, shunt trip). An auxiliary supply is required to power this product.

44mm (2.5 modules) wide DIN rail housing.
Designed to monitor and detect true RMS earth fault currents (up to 30A) in conjunction with a separate toroid.
LED bar graph provides constant indication of any leakage current.
Microprocessor controlled with internal monitoring (self-checking).
Adjustable Sensitivity (I∆n) - 30mA to 30A.
Adjustable Time Delay (∆t) - 0 (instantaneous)* to 10 seconds.
Separate “Test” and “Reset” push buttons.
Connection facility for remote “Test” and “Reset” push buttons or N.O. contacts.
Toroid open circuit detection forces unit to trip (Red LED flashes during this condition).
2 Relay outputs - Standard Output (S.O.) and Positive Safety Output (P.S.O.).
LED indication of supply status and fault condition after unit has tripped.

Supply voltage*: 12-125 VDC8(8-110% of U)(see connection diagram) 24, 115/230, 400V AC (85 - 115% of Un).
