Product Description
reaches 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.
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.
