VS1-12(550mm) miniature handcart indoor high-voltage vacuum Circuit Breaker adopts solid insulation structure, and uses advanced epoxy sealing technology to organically combine vacuum interrupter, main conductor circuit, insulating support palm, etc. into an integrated fixed air pole. Successfully solved the environmental tolerance problem of Vacuum Circuit Breaker fundamentally, making it more widely used. Self-convection ventilation technology is adopted in the integrated solid sealing pole, which skillfully solves the problem of dispersion difficulty caused by solid insulation structure.

VS1-12(550mm) miniature handcart indoor high-voltage vacuum circuit breaker is a circuit breaker that realizes the maintenance-free concept in China. Its long-life vacuum interrupter and the application of epoxy pouring sealing technology ensure the maintenance-free of the integrated fixed air pole, and the high-reliability permanent magnet operating Mechanism ensures the maintenance-free of the operating mechanism. The electronic control part abandons the traditional Auxiliary Switch and replaces it with photoelectric proximity switch, and adopts full electronic power supply and intelligent control unit to ensure the maintenance-free of the electronic control part.
