1. Product outline
The ZW6-12 outdoors high vacuum circuit breaker (hereafter refers to as circuit breaker) is the three phase ac 50Hz outdoors switching equipment. Mainly uses in the distribution network to open breaks, the pass gathers in the electrical power system the load current, the excess current and the short-circuit current. Is suitable makes the protection and the control using of to the transformer substation and in the industry and mining enterprise electrical power distribution system, is suitable the need which to the agricultural network, the city net transforms. Also may take the city urban district 12kV level electrical network section switch.
2. Use environmental condition
