摘要： A motor protection trip unit for a circuit breaker includes an electrically conductive strap, a yoke including a body including a first side wall, a second side wall, a third side wall, and a fourth side wall. The third side wall extends between the first and second side walls, the fourth side wall extending from the first and second side walls and comprising a yoke gap extending therethrough. A motor protection trip unit for a circuit breaker also includes a flapper holder coupled to the strap, a flapper pivotally coupled to the flapper holder, and a biasing mechanism coupled between the flapper holder and the flapper. The biasing mechanism is configured to maintain the flapper a distance from the yoke such that a yoke-flapper gap is defined between the yoke and the flapper.
