Abstract

A fast current limiting circuit breaker, incorporated into an electrical circuit with a circuit breaker provided with an automatic disconnector and comprising a movable contact that tends to be in the closed position of the circuit and a means for rapid displacement of the movable contact towards the open position under the effect of a sudden increase in current, which is deactivated as soon as said increase in current disappears to allow the moving contact to close automatically again.
