SOCOMEC Type A Earth Leakage Relays for Motor Load Break RESYS P40

RESYS P40 earth leakage relays associated with a remote trip breaking device (automatic power breaking), provide the following functions: - protection against indirect contact, - limitation of leakage currents. They also preventively monitor electrical installations via their (configurable) pre-alarm function or when used as signalling relays. Advantages Fully configurable • 2 relays with configurable function (alarm or pre-alarm at 50% I∆n). • Adjustmenent of I∆n from 0.03 to 30 A. • Time delay 0 to 10 s. • Positive or negative security configurable by the user. • Selection of toroid ratio. Tripping accuracy by TRMS measurement Improves immunity to nuisance tripping. Instantaneous display of permanent leakage currents The LED bargraph provides a real-time display of fluctuations in leakage currents. Compact 48x48mm panel-mounted unit The adjustment buttons are protected by a sealable cover, while the display of available alarms is displayed directly on the front face of the device. Improved immunity to EMC interferences The device has new electronics which improve electromagnetic compatibility.
