Abstract
A circuit breaker system with a shunt trip device is taught in which the shunt trip device occupies a miniature circuit breaker case and utilizes features of the miniature circuit breaker case except that it is provided with a coil and two-piece armature which initiates the shunt tripping operation when properly energized to thus open the separable main contacts of side-by-side mounted circuit breakers having the same intermediate axial member. A back plate is provided for the two-piece joined armature member in the central region of the toroid, solenoid or coil to assist the snug fit of the two-piece core within the central opening of the bobbin of the solenoid and to provide a low reluctance bypass for the magnetic flux crossing the gap formed by the end abutments of the two-pieces of the magnetic core.
