R3D415 - EARTH LEAKAGE RELAY R3D 110-24 0-415VAC

Why Choose the R3D415?

Engineered for dependable protection, the Lovato R3D415 Earth Leakage Relay (SKU R3D415) delivers precise monitoring with two operating thresholds. Designed for flush-mount panels, it works with an external CT for flexible installation and remote sensing. A multi-voltage supply of 110VAC, 240VAC or 415VAC streamlines standardisation across panels, while a clear flag indicator and fail-safe function support fast diagnostics and enhanced safety.

Built for longevity and compliance, the R3D series relay boasts a mechanical life of 50,000,000 cycles and conforms to IEC/EN 60947-2. Operating reliably from -10 to +60 °C and weighing 405 g, it suits demanding industrial environments. Practical details such as a 0.5 Nm terminal tightening torque and two configurable contacts simplify installation, commissioning and integration into new or retrofit control assemblies.
