Product Description

Product overview
ZW7-40.5
LW7-40.5 outdoor high voltage vacuum circuit breaker is used for switching load current, overload current and short circuit current of AC 50Hz three-phase power systems. It is mainly composed of vacuum arc extinguisher, CT and driving mechanism. The overall structure is pole-mounted type. The three-phase shares the same mechanism box which is water proof. This circuit breaker is equipped with spring operating mechanism or electric operating mechanism.
