ZW20 Outdoor AC HV Vacuum Circuit Breaker

Overview：

The ZW20 is three-phase outdoor vacuum circuit breaker for rated voltage 12 KV, 50Hz. The superior ability of breaking and closing load current,overcurrent and short-circuit current makes sure that it can protect the electrical circuit from damage caused by overload or short circuit reliably.

It can be used for protection and control of power distribution system in substation, industrial and mining enterprises and even more suitable for rural power network and areas with frequent operations. ZW20’s vacuumarc-extinguishing chamber is placed inside the insulating SF6 gas tank which makes it insensitive to the outside environment and to any possible aggressions such as: humidity, dust, pollution and dirt etc.
