Vacuum Circuit Breaker VCB 12kv,3-phase AC 50/60Hz VS1-12 series

 

Product Introduction

 

"High-voltage vacuum circuit breaker" is named because its arc extinguishing medium and the insulating medium in the contact gap after arc extinguishing are both vacua; vacuum circuit breakers are small in size, light in weight, suitable for frequent operation, and arc extinguishing without maintenance. Advantages, it is more popular in the distribution network.

VS1-Series VCB  vacuum circuit breakers are applicable 3-12kV, 3-phase AC 50/60Hz indoor switchgear and can serve as protection and control units for industrial and mining establishment transformer substation equipment. With the modular and independent-frame design for their spring operating mechanisms, VS1 circuit breakers can operate with KYN28 mid-set and fixed switchgear. These circuit breakers are subject to both fixed installation and assembly with the truck as a handcart unit
