ZWB-12/T630-20 Outdoor high-voltage vacuum circuit breakerDetailed product description：

ZWB-12/T630-20 outdoor high-voltage vacuum circuit breaker (hereinafter referred to as the circuit breaker) is used in power systems with AC voltage ranging from 50Hz to 12Kv. It is used for breaking, closing load current, overload current, and short-circuit current. When the circuit breaker is combined with isolation contact blades (hereinafter referred to as the combination circuit breaker), it can also be used as a section switch.

Normal usage conditions
1. Surrounding air temperature: upper limit+40 ℃, lower limit -40 ℃
2. Altitude: not exceeding 1000m
3. Wind pressure: not exceeding 700Pa (equivalent to a wind speed of 34m/s)
4. Seismic intensity: no frequent severe vibration, seismic intensity not exceeding level 8
5. Pollution level: not exceeding level III in GB/T 5582
