VSm vacuum circuit breaker is a permanent magnet vacuum circuit breaker developed by the company integrated with foreign advanced technology. It is a long-life, maintenance-free new generation circuit breaker developed by using vacuum arc extinguishing technology, permanent magnet mechanism technology and intelligent control technology. It can perform frequent operations or break the short-circuit current multiple times within the working current range; the mechanical life can be up to 30,000 times, and the full-capacity short-circuit current breaking times can reach 50 times. VSm vacuum circuit breaker is suitable for reclosing operation and has extremely high operational reliability and service life.
Products are widely used in power plants, power grids, coal mines, airports, petrochemicals, metallurgy and urban infrastructure construction and transformation projects, especially suitable for frequent operations.
VSm vacuum circuit breaker has long mechanical life, maintenance-free and high degree of intelligence. The main circuit adopts a mature insulating barrel structure, and the primary circuit adopts an assembled structure to ensure reliable insulation of the conductive circuit and easy assembly.
