Product Introduction
General
The indoor KYN28A-12 AC metal switchgear is a 3.3-12kV 3-phase AC 50/60Hz single-bus or single-bus segment distribution system for power plants, substations, industry and power. Widely used in the system. Mining companies and urban construction are used for management, protection and surveillance. The switchgear is equipped with a domestic ZN63A (VS1) vacuum circuit breaker, which has a strong circuit breaker capacity, a long mechanical life, low maintenance cost, and a long overhaul period. It can also be equipped with imported brand circuit breakers such as the Schneider HVX and ABBVD4. It can also be equipped with appliances such as JCZR16, VCF, VC, 3TL and other contactor and fuse combinations.
