Abstract
A movable contact arm set for a switching contactor includes first and second movable contact arms which respectively carry first and second movable contacts. The first and second movable contact arms respectively include first and second engagement surfaces which are engagable with an actuation to permit displacement of the first and second movable contacts. The first and second engagement surfaces are asymmetric to one another to permit asynchronous displacement of the first and second movable contacts. A switching contactor, movable contact arm for use with a movable contact arm set, and a method of providing a lead-lag contact opening arrangement for a switching contactor are also provided.
