Lovato 31RMT415 Earth Leakage Relay - Modular Residual Current Protection Relay with Integrated 28mm Toroidal Transformer 110-415VAC
The Lovato 31RMT415 is a modular earth leakage relay designed for residual current monitoring and electrical protection applications. Featuring an integrated 28mm toroidal current transformer, Type A residual current detection, configurable fail-safe operation, and compatibility with 110-125VAC/DC, 220-240VAC, and 380-415VAC supplies, this relay provides reliable earth fault protection for industrial and commercial electrical installations. The compact design allows installation on standard 35mm DIN rails according to IEC/EN 60715.
Product Overview
The Lovato 31RMT415 earth leakage relay is part of the Lovato 31RMT series of modular residual current protection devices. Unlike the standard 31RM415 version that requires an external CT, the 31RMT415 incorporates a built-in 28mm toroidal transformer, simplifying installation while maintaining accurate Type A residual current monitoring. The relay provides one adjustable operating threshold, DIN rail mounting, and configurable fail-safe functionality for enhanced system protection.
