Technical FAQs 4

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.

Are earth leakage circuit breakers safe?

Earth Leakage Circuit Breakers or ELCBs provide the utmost safety for you and your space by preventing earth faults from your equipment. With the right installation process and ELCB quality, you can be assured that your residential, commercial, or industrial space is safe from potential electrical shocks and damages.

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 is an earth leakage circuit breaker (ELCB)?

The earth leakage circuit breaker (ELCB) is used to protect persons against electric shock hazards and to prevent a fire. This also have the same function as MCCB. This type of breaker is ELCB rated 225 Amp or less, and is available to protect a motor and the associated wiring or conductors.
