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
