Abstract
A circuit breaker with improved trip unit fixation is disclosed. Another circuit breaker and a system also perform the functions of the circuit breaker. A circuit breaker includes a frame and a trip unit mounted in the frame. The trip unit includes a terminal for securing a wire to the trip unit. One of a wall of the frame and the trip unit include a protrusion and the wall of the frame or the trip unit without the protrusion includes an opening. The protrusion conforms to the opening and the protrusion and opening are positioned to oppose movement of the trip unit in a direction of a force resulting from securing the wire in the terminal.
