General
WCM5Ex series electronic plastic case circuit breaker (hereinafter referred to as circuit breaker) is one of the new circuit breakers developed by our company using international advanced design and manufacturing technology. Its rated insulation voltage is 1000V, suitable for AC 50Hz, rated working voltage 400V and below, rated working current up to 800A circuit for infrequent switching and infrequent motor starting. The circuit breaker has overload long delay inverse time, short circuit short delay inverse time, short circuit short delay definite time, short circuit instantaneous and undervoltage protection functions, which can protect the line and power supply equipment from damage.
The circuit breaker has the characteristics of small size, high breaking capacity, zero arcing (optional), etc. It can be installed vertically (i.e. vertical installation) or horizontally (i.e. horizontal installation).
