Product Description

Supply ZW8-12 / 630-20 high voltage vacuum circuit breaker, ZW8 outdoor vacuum switch



ZW8 series switch features

1. according to user needs can be installed 50 / 5,100 / 5,200 / 5,400 / 5,630 / 5 current

transformer external insulation using high-voltage silicone rubber sleeve for composite

insulation! .

2. built-in multi-tap current transformer can be used as over-current protection . !

3.The double-winding current transformer can be used for protection and measurement.

If the voltage transformer, auto-reclosing controller and auto-sectioning controller are installed,

the distribution protection automation and the functions of remote measurement, remote signal,

remote control and remote adjustment of "four remote" can be realized . . !

4.can be installed isolation switch . !
