ABSTRACT:
An apparatus and a method for quenching an arc in a gas flow circuit breaker having both a permanent current contact and an arc contact system, wherein the motion of the contacts is made current dependent, thereby delaying or accelerating the duration of the opening of the contacts of the arc contact system as a function of the current so as to shorten the arc duration and correspondingly to increase the quenching capacity of the breaker.
