A current trip unit for a circuit breaker is provided to allow electric current to flow in one direction, to prevent the electric current to flow in another direction, and to protect a rectifier. A current trip unit(10) for a circuit breaker has a lead rod(32) therein. The lead rod is a linear rod that is positioned vertically to a plate(24) and attached to the plate by fixing elements(34,36). The leading rod is attached to a base of the trip unit. The lead rod is mounted in an inside of the trip unit and is attached to be adjacent to a top of the trip unit and is attached to be adjacent to the base of the trip unit. A movable anchor(40) is slidably attached to the lead rod. The anchor lead rod is inserted through a bore adjacent to a center of the anchor. The anchor slides up and down on an axis provided by the lead rod when the anchor is operated by a magnetic yoke(18). The anchor slides on a center axis created by the lead rod.
