General
Technical Parameter

ZN63(VSI)-12 series indoor high voltage solid vacuum circuit breaker adopts solid insulation structure and advancedepoxy solid sealing technology.Vacuum interrupter,main conductive loop and insulation support are integratedinto a solid-sealed pole for the first time.The problem of environment tolerance of vacuum circuit breaker is solvedsuccessfully,which makes it more widely used.The integrated solid-sealed pole adopts the self-convectionpatented ventilation technology,which subtly solves the problem of heat dissipalion caused by the solid insulationstructure. ZN63(VS1)-12 series indoor high voltage solid vacuum circuit breaker is the first circuit breaker in China to realizethe maintenance-free concept.Its high-life vacuum interrupter and epoxy casting sealing technology ensuremaintenance-free integrated solid-sealed poles,and high-reliability permanent mognet operaling mechanismensures 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 andintelligent control unit to ensure the maintenance-free operation of the electronic control part.
