WHAT IS DIFFERENCE BETWEEN 30mA ELCB AND 100mA?

The main difference between a 30mA and a 100mA Earth Leakage Circuit Breaker (ELCB) lies in their sensitivity to earth leakage current. A 30mA ELCB is designed to provide protection against electric shock and is suitable for residential use, as it can detect smaller leakage currents, reducing the risk of injury. In contrast, a 100mA ELCB is typically used in industrial applications where the risk of electric shock is lower, as it requires a higher leakage current to trip, offering protection against fire hazards rather than direct shock.
