ELRM44V-30 EARTH LEAKAGE RELAY

Product Description

The ELRM44V-30 is an earth leakage monitoring relay designed to detect leakage currents in electrical systems and provide protection against insulation faults, equipment damage, and electrical hazards. It continuously monitors residual current through an external core balance current transformer (CBCT) and activates an output relay when the preset leakage threshold is exceeded.

This relay is widely used in industrial control panels, motor control centers, generators, switchboards, and power distribution systems where reliable earth fault protection is essential.
