Technical FAQs 4

What is an earth leakage circuit breaker?

Figure 1: An earth leakage circuit breaker An Earth Leakage Circuit Breaker (ELCB) helps protect people and equipment from electrical shocks. It detects and stops an electrical current that leaks to earth, meaning the current diverts from its intended path and flows into the ground.

What is earth leakage circuit breaker (MCB)?

MCB is a fundamental protection device used to restrict the current & fault within a circuit. The earth leakage circuit breaker works on the principles of current balancing which means it computes the net of inward current as well as outgoing current.

What is an earth leakage circuit (ELC)?

An Earth Leakage Circuit (ELC), also known as an Earth Leakage Circuit Breaker (ELCB) or Residual Current Device (RCD), is a crucial electrical safety device designed to protect people and property from electrical faults and the risk of electric shock.

What is a medium sensitivity earth leakage circuit breaker (ELCB)?

A medium-sensitivity Earth Leakage Circuit Breaker (ELCB) is an electrical safety device designed to detect and respond to ground faults or leakage currents with a moderate sensitivity threshold.
