ZW8-40.5/1600-25(20,30.5) Outdoor AC High Voltage Vacuum Circuit BreakerDetailed product description：

ZW8-40.5/1600-25 (20,30.55) outdoor AC high-voltage vacuum circuit breaker (hereinafter referred to as the circuit breaker) is used in three-phase power systems with AC 50Hz, as a switch for load current, overload current, and short-circuit current. The overall structure of this product is a pillar type ceramic bottle. The upper ceramic bottle is an arc extinguishing chamber ceramic bottle, which is equipped with a vacuum arc extinguishing chamber, and the lower ceramic bottle is a pillar ceramic bottle. The three-phase ceramic bottles are installed together in a mechanism box. The moving end of the arc extinguishing chamber is connected to the output shaft of the electromagnetic mechanism through a crank arm insulation rod. The connecting rod between the mechanism and the circuit breaker is installed in a waterproof box.
