ZN63A-12(VS1-12)Indoor AC high-voltage vacuum circuit breaker is suitable for three-phase AC50Hz, with a rated voltage of7.2KV~12KV in the power system for switching various loads of different natures and frequent operation occasions. It can be used for the protection and control of electrical equipment in industrial and mining enterprises, power plants and substations. It is one of the main high-voltage vacuum circuit breaker products of Zhejiang Chuanlong Electrical Co., Ltd. It can be equipped withKYN28A-12 (GZS1) and other middle-mounted handcart-type switchgear, and can also be equipped withXGN one-piece fixed switchgear.ZN63A-12(VS1-12) indoor AC high-voltage vacuum circuit breaker complies with the national standardsGB1984 "AC high-voltage circuit breaker",JB3855 "3.6~40.5KV Indoor AC high-voltage vacuum circuit breaker" andIEC60056 "High-voltage AC circuit breaker" standards. It meetsDL/T403 "10~35KV Ordering technical conditions for indoor high-voltage vacuum circuit breakers".
Common models:VS1-12/630-20 vs1-12/630-25 VS1-12/1250-25(31.5) Fixed type, handcart type, permanent magnet type and solid-sealed type are optional.
VS1Vacuum circuit breakers can perform frequent operations or interrupt short-circuit currents multiple times within the working current range;The mechanical life can be as high as30,000times, and the number of full-capacity short-circuit current interruptions can reach50times.
VS1Vacuum circuit breakers are suitable for reclosing operations and have extremely high operation reliability and service life.
VS1Vacuum circuit breaker(Ordinary type)uses a vertical insulating cylinder to defend against the influence of various climates;Moreover, in terms of maintenance, usually only occasional cleaning or lubrication of the operating mechanism is required.
VS1Vacuum circuit breaker(Pole type)uses a solid insulation structure - integrated solid-sealed pole, achieving maintenance-free operation.
VS1Vacuum circuit breakers can be installed in switchgear in either a fixed or withdrawable form, and can also be installed on a frame for use.
