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.
