ELCB AND RCCB (RCD) Earth Leakage Circuit Breaker (ELCB) Working Principle of ELCB An Earth Leakage Circuit Breaker (ELCB) is a security device used in an electrical installation to detect leakage current and protect humans against the risk of an electric shock, from this leakage current. The operation is such that, the power supply connected at its switching terminal (contact of the circuit breaker) is disconnected by a special type of latching relay when it detects a leakage current. Thereby, protecting individuals getting in contact with this leakage current against the risk of an electric shock. This circuit breaker remains OFF until reset manually. Types of Earth Leakage Circuit Breaker They are two types of Earth Leakage Circuit Breakers. They are named based on their principle of operation. They are; The Voltage Earth Leakage Device (Known as the ELCB) and The Current Earth Leakage Circuit Breaker (RCD or RCCB). In the past, when referring to Earth Lea...
