Earth leakage breaker factory in Mauritania

What is earth leakage circuit breaker?

The earth leakage circuit breaker canprotect overload and short-circuit of the circuit or motor, it can also be converted and started infrequently under normal circumstances. The earth leakage circuit breakers meet the standards of GB16917.1-2003 and IEC61009-1, the product obtains design the national patent certificate.

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.

What are earth leakage protection devices?

Earth leakage protection devices are crucial for electrical safety, preventing electric shocks and fires caused by faulty wiring or insulation failures. Three common devices used for this purpose are Earth Leakage Circuit Breakers (ELCBs), Residual Current Devices (RCDs), and Residual Current Circuit Breakers with Overcurrent Protection (RCBOs).

Can overcurrent protection devices operate if Earth faults are too low?

We’ve often seen the cases that the current flowing due to earth faults is too low to operate the overcurrent protection devices. It’s important to note that the overcurrent protective device will not operate in the event of somebody making direct contact with a live conductor.
