Earth leakage breaker factory in Suriname

How does an earth leakage circuit breaker work?

Our earth leakage circuit breaker is generally composed of a ZCT (Zero-phase-sequence Current Transformer) + Earth leakage relay + Circuit breaker. The ZCT detects earth leakage current, notifies the electronic circuit, and shuts off the circuit using an internal tripping device.

Can an earth leakage circuit breaker cause a fire?

A leakage current of 100 mA or more can cause a fire. An earth leakage circuit breaker detects earth leakage of approximately 15 to 30 mA, and immediately shuts off the circuit within 0.1 seconds, preventing an accident.
