Detailed Product Description
WCM4 series moulded case circuit breaker MCCB is the new product of our company. The designation represents the best current limited principle and making technology. Structure compact, full moulded, high breaking capacity, zero arc distance,etc. Worked in the circuit of R. insulating voltage is 750V, apply with AC50Hz, R. operating voltage 690V or below, R. operating current up to 630A. Used for switch on or switch off motor not frequently. The circuit breaker can prevent the device from damage when overload, short circuit or lack of voltage.
WCM4 series has 4 type as N type(standard), H type(higher capacity), L type(current limited) according to the R. ultimate short circuit breaking capacity.
The circuit breaker can be installed vertical and horizontal. Do not connect reverse.
