31RM415 - MODULAR EARTH LEAKAGE RELAY RM 110-415VA

Why Choose the 31RM415?

Lovato’s 31RM415 earth leakage relay delivers dependable Type A residual protection in modular control panels. Designed for 35 mm DIN (IEC/EN60715) rail mounting, it works with an external toroidal transformer and provides a single operating threshold for straightforward setup. A wide rated supply range of 110…125VAC/DC and 220…240/380…415VAC makes integration simple across mixed-voltage installations.

Built to last, the RM-series device offers a mechanical life of 50,000,000 cycles and operates from -10 to +60 °C. With a maximum terminal tightening torque of 0.5 Nm and compliance to IEC/EN 60947-2, it supports robust, standards-based protection. At just 190 g, it’s a practical choice for space-limited panels and OEM assemblies.
