Abstract
1462691 Automatic circuit breakers MATSUSHITA ELECTRIC WORKS Ltd 3 April 1974 [5 April 1973 6 April 1973] 14756/74 Heading H1N A circuit breaker has an insulating casing divided by a horizontal partition 3, the upper compartment housing the actuating mechanism D (forming the subject of Specification 1,462,692) and the lower compartment housing the contacts B and overload trip C (shown from below in Fig. 8). Arc overload-trip armature 25 and a shift element 22 pass through slots in the partition 3, the shift element effecting movement of the contacts. Rotation of the control lever 57 to ON position results in clockwise rotation of arm 40, the end 40a engaging shift element 22 to move it against the spring 23. Contact arms 12 pass through slots in the shift element 22 and are thus moved with it to close the contacts. Energization of any of the trips C results in attraction of armature 25, a projection thereon striking member 49 (Fig. 7) thus disengaging it from the latch 42 to release the arm 40 and shift element 22 which is returned by the spring 23 to open the contacts. The arrangement is "trip-free" and the handle is fitted with a plate to indicate the operating condition of the breaker.
