A mobile application including a motive power circuit including a power storage device and an electrical load, where the power storage device and the electrical load are selectively electrically coupled through a power bus; a power distribution unit (PDU) electrically interposed between the power storage device and the electrical load, wherein the PDU comprises a breaker/relay including: a fixed contact electrically coupled to the power bus; a movable contact selectively electrically coupled to the fixed contact; an armature operationally coupled to the movable contact; a first biasing member biasing the armature; a contact force spring operationally interposed between the armature and the movable contact; and a means for adjusting an opening velocity of the moveable contact during a run-time operation of the power bus, wherein the opening velocity comprises an initial velocity of the moveable contact away from the fixed contact in response to a physical opening response.
