Earth Leakage Circuit Breakers (ELCB)

Wide assorted products which is suitable for protections of an overload, a short circuit and a electric shock in low voltage circuit.

These are basic products for the protection of the low voltage circuit. The WS-V series, Mitsubishi's latest Low Voltage Circuit Breakers, prepares various variations including "F-style" of small size breakers and improves the usability of them.

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".
