Outline

1.1 Product model and name

ZW1-12 outdoors high vacuum circuit breaker

1.2 Main use and working condition

This circuit breaker is the three phase ac 50Hz outdoors high-voltage switch equipment, mainly uses for to break, Guan Henong the network, the city net and the small electrical power system load current, the excess current and the short-circuit current

This product is suitable for the below working condition:

a. Surrounding air temperature -30 ℃ ~ +40 ℃

b. The elevation does not surpass 2000m

c. The wind pressure does not surpass 700Pa (to be equal to wind speed 34m/s)

d. Non- regular fierce vibration
