The AMVAC circuit breaker is an ANSI-rated vacuum circuit breaker.
The AMVAC circuit breaker combines maintenance-free epoxy encapsulated vacuum interrupters, with a maintenance-free 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.
