£438.92
The Lovato 31RM415 is a modular earth leakage relay designed for residual current monitoring and electrical protection applications. Featuring Type A residual current detection, a single adjustable operating threshold, and compatibility with 110-125VAC/DC, 220-240VAC, and 380-415VAC supply systems, this relay provides dependable earth fault protection for industrial and commercial electrical installations. The unit is designed for 35mm DIN rail mounting and requires an external toroidal current transformer.
The Lovato 31RM415 earth leakage relay is part of the Lovato 31RM series of modular residual current monitoring devices. It is designed for installation on IEC/EN 60715 35mm DIN rails and operates with an external toroidal transformer to monitor leakage currents. The relay provides one adjustable operating threshold, SPDT output switching, and Type A residual current detection suitable for AC and pulsating DC fault currents.
The Lovato 31RM415 is suitable for electrical systems requiring reliable earth leakage monitoring and residual current protection, including:
The Lovato 31RM415 provides a flexible and reliable residual current monitoring solution for DIN rail applications. Its modular design, external CT compatibility, Type A detection, and wide supply voltage range make it suitable for protecting electrical systems where accurate earth leakage monitoring is required.
