12kV · IEC · manufactured by Shanghai Jingmin Electric, China.
A vacuum circuit breaker interrupts load current and short-circuit current by drawing an arc in vacuum, where it is extinguished within half a cycle. Outdoor pole-mounted types protect overhead lines; indoor types sit in switchgear cubicles.
Our breakers use vacuum interrupters and spring or permanent-magnet actuators, tested to IEC 62271-100, with mechanical life of 10 000 operations.
