ANSI Vacuum Magnetic Circuit Breaker AMVAC

The AMVAC circuit breaker is an ANSI-rated vacuum circuit breaker.

The AMVAC circuit breaker combines maintenance-free epoxy encapsulated vacuum interrupters, with an ultra-low maintenance magnetic actuator mechanism, and a maintenance-free electronic controller. The electronic controller not only maintains the charge in the long life capacitors used for open/close operations, but also controls the open, close, and anti-pump functions. The AMVAC breaker requires the least maintenance of all medium voltage vacuum circuit breaker designs in the market today.
