General

WCM1L sereis residual current protection moulded case circuit breaker (ELCB for short) is one new breakers researched and devleloped by advanced international design and manufacture technolgy. The rated insulation voltage is 800V, applies AC 50Hz, rated operation voltage 400V, rated operation current upto 630A for infrequent switch of the line and infrequent start of the motor. ELCB has protection functions to overload, short circuit and under-voltage, to protect the line and power device from demage, also make protection to the fire caused by grounding fault at long time that undected under over current.
ELCB is divided into Type M (higher breaking) and Type H (highest breaking), has features of small 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.
