Product Description

General:
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 capability 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.
Main features:
1.Mechanical and electrical durability During rated current, breaking times can reach to 10000, 20000 During rated
short-circuit current, breaking times can reach to 20, 30 and 50 times.
2.The circuit breaker has complete functions. It is used to switch on/off various loads as specified by DL standards, such as method 1-5, capacitor, out-of-phase conditions.
3.Easy maintenance Normally, it just needs to clean the operating mechanism and add lubricants.
4.Vertical insulating tube Protect it from various environmental impacts.
5.With complete product portfolio Rated current from 630A to 5000A Rated short-circuit current form 20kA to 50kA
6.It has the features of series, strong versatility, convenient use and easy maintenance. All products have passed 100 running-in tests according to reliability principle in the factory before delivery, so as to ensure the reliability
