ZW50-40.5 Outdoor high-voltage vacuum circuit breakerDetailed product description：

The ZW50-40.5 series outdoor high-voltage vacuum circuit breaker is an outdoor distribution equipment with a rated voltage of 40.5kV and three-phase AC 50Hz. Suitable for protection and control in urban and rural power grids, and more suitable for places with frequent operations. The circuit breaker adopts a brand new miniaturized design, fully enclosed structure, and unique vacuum arc extinguishing chamber sealing technology, with good sealing performance, which helps to improve moisture-proof and anti condensation performance, and is suitable for use in high-temperature and humid areas. Unique structural design, the current transformer and circuit breaker are integrated, which can achieve measurement and protection functions. The closing and opening of the circuit breaker can be manually or electrically operated, and can also be remotely controlled.
