Product Description
VS1-12 side mounted vacuum circuit breaker indoor high voltage switchgear, suitable for rated voltage 12 kV, frequency 50Hz three-phase power system, as a protection and control appliances used, due to the special advantages of vacuum circuit breaker, especially suitable for frequent operation of rated current, or multiple times to break the short circuit current.
VA1-12 type side mounted vacuum circuit breaker adopts fixed installation, mainly used for fixed switch cabinet, the breaker can be used alone, but also can be used for ring network power supply, box type transformer or various non-standard power supply system.
Model And Meaning
Performance Advantage The product is equipped with a bistable permanent magnet operating mechanism, the mechanism is equipped with a permanent magnet, by the permanent magnet to provide a holding force, so that the switch is maintained in the open and closed state, compared with the conventional spring operating mechanism, the number of mechanical parts is reduced, the mechanical transmission chain is shortened, so that the reliability of the switch is greatly improved, the mechanical life is greatly increased.
