Product Description

ZN63 (VS1) type indoor high voltage vacuum circuit breaker

Product overview


VS1 (ZN63A) type indoor high voltage vacuum circuit breaker (hereinafter referred to as circuit breaker) is the indoor switchgear used for 12kV power system, power grid equipment as well as protection and control unit of the power equipment in industrial and mining enterprises. Due to its special merits, vacuum circuit breaker is in particular suitable for frequent operation at rated working current or for multiple times of short circuit current breaking.

It is of operating mechanism and circuit breaker integrated design. It can serve as the fixed installation unit or be equipped with the special feed mechanism to form the withdrawable unit.
