VCBI(VS1)-15kv Series High-voltage Breaker

VCBI(VS1)-15kv Series High-voltage Breaker
Product Detailed
VCBI(VS1)-15KV Indoor AC High Voltage Vacuum Circuit Breaker ISO9001:2008 IQNet&CQC IEC 62271, GB 1984, JB3855 and DL1403.

Description of VCBI -15                                                                      

VCBI series high-voltage vacuum circuit breaker is a kind of indoor high-voltage switch equipment with 50/60Hz three-phase alternating current and 15kV rated voltage, which combined the technique of the ABB Corporation in Switzerland and domestic development state and manufacturing capability. The general framework is composed by the body and operation system.

The composite insulated material insures no pollution and explosion danger with high insulation level.

The product conforms to IEC 62271, GB 1984, JB3855 and DL1403.
