RESYS M40 type A differential relay (earth leakage protection) RESYS M40 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 a (configurable) pre-alarm function or when used as a signalling relay. Features: Positive or negative security 2 relays with configurable function (alarm or pre-alarm at 50% (I△n) Adjustment of I△n: 0.03 – 0.1 – 0.3 – 0.5 – 1 – 3 – 5 – 10 – 30A Time delay: 0 – 0.06 – 0.15 – 0.30 – 0.50 – 0.80 – 1 – 4 – 10 second Modular DIN rail mountable (same format as MCB’s) 44mm wide LED bargraph provides real-time display of leakage currents Tripping accuracy by TRMS measurement (improves immunity to nuisance tripping) SERIES RESYS M40 CURRENT SETTING I△n 0.03 – 30A TIME DELAY (SECOND) 0 – 10 ADJUSTMENT OF I△n 0.03 – 0.1 – 0.3 – 0.5 – 1 – 3 – 5 – 10 – 30A POWER SUPPLY 115/230 VAC MOUNTING Modular DIN rail (same format as MCB’s) 44mm wide DESCRIPTION Electronic earth leakage relay
