R1D415 - EARTH LEAKAGE RELAY R1D 240-41 5VAC FLUS

Why Choose the R1D415?

Engineered for dependable residual current protection, the Lovato R1D415 Earth leakage relay combines Type A sensitivity with robust flush mounting for neat panels. Designed for use with an external toroidal transformer, this single-threshold relay operates across 110…125VAC/DC and 220…240/380…415VAC supplies, delivering fast, reliable detection of leakage faults to help prevent equipment damage and enhance operator safety in industrial and commercial installations.

Part of the R1D series, it meets IEC/EN 60947-2, supporting assured compliance. Built for longevity with a mechanical life of 50,000,000 cycles, it performs from -10 to +60 °C and stores at -20 to +80 °C. Installation is straightforward with flush mounting and terminals rated up to 0.5 Nm; compact 280 g construction suits dense panels and retrofit upgrades.
