ZN63(VS1)-12

Indoor High Voltage Vacuum Circuit Breaker With embedded pole

ZN63(VS1)-12 series indoor high voltage solid vacuum circuit breaker adopts solid insulation structure and advanced epoxy solid sealing technology. Vacuum interrupter, main conductive loop and insulation support are integrated into a solid-sealed pole for the first time.The problem of environment tolerance of vacuum circuit breaker is solved successfully, which makes it more widely used.The integrated solid-sealed pole adopts the self-convection patented ventilation technology, which subtly solves the problem of heat dissipation caused by the solid insulation structure.

ZN63(VS1)-12 series indoor high voltage solid vacuum circuit breaker is the first circuit breaker in China to realize the maintenance-free concept.lt's high-life vacuum interrupter and epoxy casting sealing technology ensure maintenance-free integrated solid-sealed poles,and high-reliability permanent magnet operating mechanism ensures maintenance-free operation of the operating mechanism. The electronic control part abandons the traditional auxiliary switch, uses the photoelectric proximity switch, and uses the fully electronic power supply and intelligent control unit to ensure the maintenance-free operation of the electronic control part.
