Abstract
A multiple circuit breaker system wherein each single pole breaker within the multiple breaker system have very similar structure and dimensions, except that at least one of the breakers (e.g. the one which is connected to a floating neutral pole) has an additional articulation which the other breakers do not have. This additional articulation, and the associated spring action, provide extended contact time.
