Overview

Socomec RESYS P40 (SKU 49423711) is a Type A earth leakage relay designed for motor circuits. It protects against indirect contact and limits earth leakage currents with adjustable IΔn settings from 0.03A to 30A. The device features TRMS monitoring for trigger accuracy, a real-time LED bargraph for leakage current visualization, and two configurable relays (alarm or pre-alarm at 50% IΔn). It includes a 0-10s time delay, positive/negative security settings, and enhanced EMC immunity. Housed in a compact 48x48mm sealed case, it meets IEC 60755, IEC 60947-2, IEC 60664, and IEC 61543 A1 standards. Ideal for energy, industrial, and building applications, it prevents accidental power cuts and reduces fire/explosion risks in BE2/BE3 areas.
