ZN63(VS1)-12 side mount series high voltage vacuum circuit breaker

VS1-12 side type vacuum circuit breaker is a indoor high voltage switch equipment, applicable to 12 kv rated voltage, three-phase power system frequency 50 hz, used as protection and control electric equipment, because of the special superiority of vacuum circuit breaker, especially suitable for need rated power flow frequent operation, or more open circuit short circuit current.

The vs1-12 side mounted vacuum circuit breaker adopts fixed installation, which is mainly used for fixed switch cabinet. This breaker can be used alone, and can also be used for ring network power supply, box type transformer or various non-standard power supply systems.
