Earth Leakage Relays

Earth Leakage Relays


Variable Earth Leakage Relays in compact 35mm din rail mounting cases for use on 3 phase electrical systems.


To monitor earth leakage current and to operate an associated relay at a preset current. May be used to shut down a system or operate an alarm under fault conditions.

ELR’s are fitted with test and reset buttons. Pressing the test button allows a fault to be simulated and the output relays operate accordingly. Pressing the reset button after a fault occurs restores the unit back to its normal operation. A red LED light will illuminate after the unit trips due to an excessive fault current.
