Mô tả
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.

Earth-Leakage Circuit Breakers
Earth leakage circuit breaker:ELCB is a molded case circuit breaker used in a low voltage AC circuit to provide electrical shock protection and prevent fires from leakage current.As a general abbreviation, ELCB in our model name is denoted as "NV".Construction
ELCB is defined as a "device with integrated ground fault detector, tripping device and switch mechanism in an insulated body, and automatically shuts off the electric current in the event of a ground fault".To avoid nuisance operation caused by high harmonics or surge
Digital filter
Even with the inverter circuit with digital filter circuit, a part with the sensitivity current as a general circuit can be selected.

DPDC surge discrimination
A DPDC surge discriminating circuit is incorporated. It is judged as a ground fault and the circuit breaker functions only when the ground fault current polarity alternates with the positive/negative poles for a set time. Thus, the circuit breaker operates accurately without incorrectly tripping at a lightning surge, etc.
