Product Description

General

WCM1L series residual current protection moulded case
circuit breaker (RCCB for short) is one new breaker
researched and developed by advanced international
design and manufacture technology of the company.
The rated insulation voltage 800V, applies AC50Hz,
rated operation voltage 400V, rated operation current
upto 800A for infrequent switch of the line and infrequent
start of the motor. RCCB has protection functions to
overload, short circuit and under voltage, to protect the
line and power device from deamge, also make protection
to the fire caused by Grounding fault at long time that
undetected under over current.
RCCB is divided into type M (higher breaking), and type H
 (very high breaking), has features of smal volume, high
breaking, short flashover, vibration resistance, etc.,

Notes: 1. It includes vertical and horizontal installation of ultimate breaking and flashover distance;
            2. Three poles circuit breaker of this series connects with three phase loading, of which can not be with neutral line, otherwise the circuit breaker will make fault operation;
           3. Three poles circuit breaker of this series connects with three phase loading, phase line at left pole, neutral line at right pole not the middle pole.
