VS1 24KV Vacuum Circuit Breaker with Common Insulated Cylinder (ISO9001-2000)
General Description
VIB-24 series of Indoor High Voltage Vacuum Circuit Breaker with Common Insulated Cylinder is three phase A.C.50Hz
indoor power distribution equipment with the rated voltage of 24KV. It's used for protecting and controlling the electrical
equipment in the fileds of industry & minning 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 adopt composite insulation way,spring charged operation and screw rod push mechanism,
with the characeristics 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 KYN28-24(GZS1), This series of products include:VCB truck,isolation truck and fuse truck etc.
