Abstract
1393799 Automatic circuit-breakers TOKYO SHIBAURA ELECTRIC CO Ltd 27 Oct 1972 [1 Dec 1971] 49592/72 Heading H1N A circuit-breaker has a toggle linkage 26, 33 interconnecting a pivoted operating handle 25 and a pivoted contact-carrying arm 18, a releasable member 34 having one end forming a pivot of the linkage and its other end guided in elongated slots 221 and latched by a pivoted latch 35, and overload responsive means to move the latch to release the member 34 so that the circuit-breaker contacts 30, 15 open. In the closed position shown, the contacts are maintained closed against spring bias by the member 34 and by the toggle formed by the handle 25 and upper link 26 being overcentre. On overload a coil (not shown) attracts an armature 40 which abuts and moves the latch 35 to release the member 34. The toggle linkage collapses to open the contacts and a spring (not shown) restores the handle 25 to the "off" position so that the latch 35, member 34 and the links are automatically reset ready for a subsequent manual reclosing operation.
