Industrial controls 12KV VS1 outdoor vacuum circuit breaker VCB

HWZN63(VS1) outdoor vacuum circuit breaker (hereinafter referred to as circuit breaker) is outdoor distribution equipment with rated voltage of 12kV and three-phase ac of 50Hz.It is mainly used for load current, overload current and short circuit current in power system.It is suitable for protection and control of power distribution systems in substations and industrial and mining enterprises.

This circuit breaker has the characteristics of small size, light weight, anti-condensation, rabbit maintenance and so on, can adapt to the harsh weather conditions and dirty environment.

1. The rated current 4000A switch cabinet needs to strengthen the air cooling
2 When the rated short-circuit breaking current is less than 40KA, Q = 0.3s; when the rated short-circuit breaking current is greater than or equal to 40KA, Q = 180s
