Product overview

VS1 vacuum circuit breaker is used in 12kV, 24KV three-phase AC 50/60Hz indoor switchgear, and can be used for the protection and control of industrial and mining enterprises and substation equipment. The spring operating mechanism of VS1 series circuit breaker is a modular independent frame design, installed in KYN28-12 (24) centralized and fixed switch cabinets. The VS1 circuit breaker can be fixedly installed or used in combination with a trolley.

VS1-Series circuit breakers are Class M2.c2 and E2 model

VS1 series circuit breakers are maintenance-free and can be operated frequently. Compared with traditional circuit breaker products, the mechanical durability of VS1 circuit breaker has been improved from 10,000 ops to 20,000 ops, which is a huge improvement. The type test of capacitive current interruption shows a very low probability of re-arcing. VS1 has a long electrical life and free maintenance.
