Product detail
ZW32-40.5 outdoor high-voltage intelligent (permanent magnet) vacuum circuit breaker is mainly composed of integrated solid-sealed pole, current transformer, operating mechanism and cabinet. An isolating switch can be installed. This type of circuit breaker has a miniaturized design, and the shell is made of high-quality steel box. The current transformer can be selected according to user needs.
The device is mainly used in medium-voltage overhead line power grids for dividing and combining load current, overload current and short-circuit current.
