AMVAC technical guide Vacuum circuit breaker with magnetic actuator mechanism
All operating mechanism functions are integrated in the magnetic actuator of the AMVAC circuit breaker. The actuator is a bi-stable magnet system, in which armature change-of-state is accomplished by the magnetic field of two electrically excited coils. The armature is held magnetically in the limit positions by the fields of two rare-earth
