Earth leakage relays are used in combination with Core balance current transformers (CBCT) or Zero phase current transformer (ZCT). During an earth fault, the current flows directly to the …

Selec ELR341, digital Earth Leakage Relay for 1Ø & 3Ø systems, Monitors True RMS Earth Leakage Current with upto 30A. Protects & warns against leakage current. DIN-rail mount, CE certified.

Earth Leakage Circuit breaker (ELCB or RCCB) has integral current breaking device. It detects as well as protects the system by opening the protected circuit when the residual current exceeds the set value. ELR is a relay that send a signal to the shunt coil of a circuit breaker (MCB/MCCB or ACB) whenever the leakage current exceeds the set level.

Protection is achieved in combination with the MCBs and MCCBs. Compliance with protection standard IEC/EN 60947-2 Annex M allows to offer a cumulative operational time (residual current relay, shunt-trip, circuit breaker) guaranteed by the manufacturer. The new ABB ELR front panel residual current relays are tested for this purpose.

Earth Leakage Relay (ELR) An earth leakage can represent a danger to life or property if it is not located and mitigated. Studies have revealed that at least 500 people experience electrocution every year in the US alone. Earth leakage relays can be helpful in sensing and mitigating such incidents. Table of contents
