Abstract
An electromagnetic circuit breaker in which the mechanism for the circuit breaker is supported on the frame, in turn, supported on a base. Cooperative with the base is an insulating housing enclosure which is moved over the mechanism and into a fixed latching engagement with the base using detents or other indexing devices. The electromagnetic coil for the breaker is supported on a bobbin, in turn, supported on a platform on the frame. A non-magnetic tube contains the magnetic core which is biased away from the pole piece closing the end of the tube. At the pole piece end of the tube a radially extending flange of the tube engages the other flange of the bobbin and supports the tube to extend through the hollow core of the bobbin and the coil wrapped thereon. Shoulders are provided on the sidewalls of the housing enclosure in position such that as the housing enclosure is brought into latched engagement with the base, the shoulder will engage the flange and press it against the bobbin, thereby clamping the tube and the coil on its bobbin in fixed position relative to the frame. In preferred embodiments flange extensions from diametrically opposite sides of the flange are accommodated by channels in the sidewalls guiding the extensions into contact with the shoulders.
