Audited Supplier Get ready to experience the power of the ZN63(VS1)1-12 indoor M.V.! This indoor switchgear is perfect for industrial and mining enterprises, power plants, substations, and electrical facilities. With a tri-phase AC 50Hz and a rated voltage of 12kV, this switchgear is designed for frequent operation and offers control and protection like no other.
The VET operating mechanism and circuit breaker integrated design make this switchgear a fixed installation unit that can also be equipped with special advance mechanisms. The handcart unit used in the composition of this switchgear can use the whole solid seal post with high reliability and is maintenance-free. Plus, it's designed to achieve a smaller circuit breaker, making it even more efficient.
For those looking for even more options, the ZN63 can be used with the fixed XGN switchgear or equipped with the KYN2BA 12(GZS) and other handcart switch cabinets. And if you're wondering about the difference between the ZN63 and ZN83 mechanisms, don't worry! All ZN83 mechanisms can be replaced by ZN63 mechanisms, making them universal mechanisms.
