Abstract
A circuit breaker having an arc suppressing means disposed adjacent a contactor section and including a first arc running plate extended from a fixed contactor and a second arc running plate opposed to the first arc running plate. The distance between the both arc running plates on the side close to the contactor section is minimized so as not to cause any spatial short-circuiting to occur. At portions of the both arc running plates defining the minimized distance, magnetic arc driving force motivated by mutually oppositely directed arc currents flowing through the respective arc running plates is increased to a large extent, whereby arc shifting to deion grid of the arc suppressing means can be performed effectively quickly.
