Abstract
A unitized combination starter is constructed with circuit breaker and contactor sections, each of which is provided with a pair of spaced stationary contacts and a cooperating movable bridging contact. The bridging contacts are closely spaced, are parallel and carry currents which flow in opposite directions. Under severe fault conditions a strong blowoff effect is created to force both bridging contacts in their respective contact opening directions. This quickly places four air gaps in the current path to severely limit current rise and thereby facilitate circuit interruption.
