ABSTRACT A remotely controllable circuit breaker with an improved space saving structure comprises first and second movable contacts and which are held respectively on first and second contact arms and and are driven individually by a switching mechanism including a manual handle with a contact tripping capability and by a remote control signal responsive electromagnet . An L-shaped actuator with a horizontal member and a vertical member is provided to operatively connect the second contact arm to an axially movable core , the output member of the electromagnet . The actuator is pivoted at its connection between the horizontal and vertical members and and carries the second contact arm on its vertical member for pivotal movement of the second contact arm between operative and inoperative positions respectively enabling and disabling the contact closing. The electromagnet is arranged in side-by-side relation to the switching mechanism with the first and second contact arms and interposed therebetween. The actuator is located in proximity to the electromagnet with the vertical member extending over the lengthwise dimension or the axial direction of the core and with the horizontal member extending over the width dimension of the electromagnet to thereby accommodate the substantial portion of the actuator within the lengthwise and widthwise dimensions of the adjacently disposed electromagnet .
