air circuit breaker

1.no pollution 2.no explosion danger 3.high insulation level 4.different operation modes

Description

VS1 series vacuum circuit breaker is the high voltage indoor switch equipment,and the rated voltage is 12kv,three phase AC 50HZ,we introduced the high technology from Switzerland ABB company,and combined our own industry development,production capacitity ,then we reseach and develop the newest product.

The operation structure  of VS1series is spring store.it can be uesd by motor-drive,as well as manual operation
