Circuit Breaker
Solid sealed vacuum circuit breaker
Product Introduction
VAS1-12 series sealed vacuum circuit breakers are indoor AC high-voltage switchgear, which are suitable for three-phase AC power system with rated voltage of 12kV and frequency of 50Hz, and used as protection and control appliances. Widely used in indoor air-insulated switchgear. It conforms to GB/T1984, DL/T403 and other related standards, and its performance meets the requirements of C2-E2-M2 circuit breakers. VAS1-12 series sealed vacuum circuit breakers can meet all kinds of operation of power grid in normal or accident state, including closing and breaking load current and short-circuit current.
Product Model
According to different authorized companies, the main models of products are Blockset, 8PT and Mdmax.
Product Features
The three poles of VAS1-12 series sealed vacuum circuit breaker adopt automatic pressure gel process (APG), and the vacuum interrupter and the upper and lower outlet terminals are vacuum die-cast with epoxy resin, which reduces the adjustment links of the circuit breaker, effectively prevents the vacuum interrupter from being damaged by external impact, pollution and condensation, and has no interphase flashover, and increases the external climbing distance of the main circuit, thus improving the reliability of the circuit breaker.
