Description
Description
VS1(ZN63A)-12C series side mounted type indoor high voltage vacuum circuit breaker, is three-phase AC 50HZ indoor high voltage switchgear with rated voltage 12kV, used as protection and control electrical equipment. This VCB is specially used for the locations of frequently operation based on the rated current, or multiple breaking short circuit current.
The side mounted circuit breaker is designed as a fixed type mount, and mainly used in fixed type switchgear. It can be used separately, also be used for Ring Main Unit, substation and non-standard power supply system.
