Product Description

General

WCM4 sereis moulded case circuit breaker (MCCB for short) is the new type of product with top current limiting principal and manufacture technology in design, is tight in structure, total molularized, high breaking capacity, zero flashover. It applies at AC50Hz, rated operation voltage 690V and below, rated operation current upto 1250A for infrequent switch of line and infrequent start of motor. MCCB has overload, short circuit and under voltage protection device, to protect line and power device from demage.
MCCB is divided into Type S (Standard), Type H (higher breaking capacity), Type L (current limiting) according to rated ultimate short circuit breaking capacity (Icu) ranking.
