Contact Arms Featuring Current Limiting And Blow Out Capabilities In A Circuit Interrupter
Abstract: The invention provides a circuit interrupter incorporating profiles designed to facilitate arc blow out action during circuit interruption. Accordingly, as per a single break embodiment of the invention a first contact arm is designed to have a part substantially parallel to the arc initially created during contacts opening. In order to provide arc-repulsing forces along continued arc time, a second contact is provided with a profile, which offers repulsive forces on the arc as the parting between the contact arms increases. As per another embodiment of the invention the contact arm featuring arc blowout and current limiting capabilities arc incorporated in a rotary double break circuit interrupter.
