Indoor Circuit Breakers

VS1- 12 (ZN63-12) side-mounted type vacuum circuit breaker is a kind of indoor high voltage switch device which is used in the AC thee-phase power system of frequency 50/60Hz. rated voltage 12KV to be the protection and control unit. Because of the special superiority of vacuum circuit breaker, especially suitable for applications that require frequent operation at rated operating current or multiple open short-circuit breaking curent location. It is especially suitable to the place requiring frequent operations.
VS1- 12 (ZN63-12) side- -mounted type vacuum circuit breaker adopts fixed insallation, which is mainly used in the fixed switchgear. It can be used alone or used in ring network power supply system, box-ype variable system and non-standard power supply system to protect and control the Tansmission and disribuion line.

 ZN63(VS1) indoor high-voltage alteratingcurrent vacuum circuit breaker has a frequency of 50Hz and a rated voltage of 12kV. It applies to the ecrical equipment control and protection in industial and mining enterprises, power plants and substations, priculanty to the places needing frequent operation. It can be fixed in a switch cabinet or nstalld on a handcart.
 With stable performance and convenient intallation, it is the best choice for the control and protection of hig-voltage power transmission and distribution systems.
