Product Description
Product DescriptionVs1-12 type side-mounted vacuum circuit breaker is an indoor high-voltage switchgear, which is applicable to the three-phase power system with rated voltage of 12 kV and frequency of 50 Hz. It is used as a protection and control appliance. Due to the special advantages of vacuum circuit breaker, it is especially suitable for frequent operation under rated current, or places where the short circuit current needs to be broken for many times.
VS1-12 side-mounted vacuum circuit breaker adopts fixed installation, mainly used for fixed switch cabinet. The center breaker can be used separately, as well as for loop network power supply, box-type transformer or various non-standard power supply systems
