Adjustable Current Leakage Circuit Breaker ELCB

Adjustable Current Leakage Circuit Breaker ELCB is a device that can detect leakage in the circuit and automatically cut off the power supply. It is mainly used to protect personal safety and prevent electrical fires. When the leakage current in the circuit reaches or exceeds the preset value, the ELCB can quickly cut off the power supply, thus avoiding electric shock accidents and electrical fires. At the same time, it also has overload and short-circuit protection functions.

Principle of operation

The operation of the Adjustable Current Leakage Circuit Breaker ELCB is based on the principle of the balance of currents. Under normal conditions, the currents in the Fire (L) and Zero (N) wires of an electrical circuit are equal. When a leakage occurs, part of the current in the fire wire flows through the human body or the grounding body to the earth, resulting in an imbalance of current in the fire wire and the zero wire. the ELCB detects this imbalance of current to recognize the leakage and automatically cuts off the power supply.
