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.
