Product Description

 

Product Description

General
WCM9Z series photovoltaic dedicated DC Moulded case circuit breakers are suitable for DC grid circuits with rated voltage up to DC1500V and rated current 630A. The DC circuit breakers have overload long-delay protection. Short-circuit instantaneous protection function is used to distribute electric energy and protect lines and power equipment from overload, short-circuit and other faults. The operating mechanism of the DC circuit breaker has quick closing and quick breaking functions. It has a compact structure, small size and is easy to use.
This product complies with the requirements of GB 14048.2 and IEC/EN 60947-2 standards.
