Product Description VS1-12 series of indoor
vacuum circuit breaker with common insulated cylinder is
three-phrase A.C. 50 Hz indoor power distribution equipment with
the rated voltage of 12KV. It' s used for protecting controlling
the electrical equipment in the fields of industry and mining
enterprise, power plants and substation.This type vacuum circuit
breaker conforms to national standards and the stipulation of IEC
standard, the capabilityreaches grade of M2-E2-C2. The
product adopts composite insulation way,spring charged operation
and rod push mechanism,with the characteristics of small volume,
compact design and reliable operation. It can easily match with the
switchgear and meet the "Five Preventions" demands.
This kind of vacuum circuit breaker can be used for many kinds of
switchgear like KYN28(GZS1). This series of products include: VCB
truck isolation truck and Fuse truck, etc.Model And
MeaningPerformance 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.Product Display Product
