Abstract
1,194,077. Automatic circuit-breakers. ELLENBERGER & POENSGEN G.m.b.H. 31 July, 1968 [2 Aug., 1967], No. 36579/68. Heading H1N. In a trip-free overload-responsive circuitbreaker of the kind having an angled bridging contact 19 freely pivoted on an axially-movable control member 28, a bi-metallic strip 9 with a contact plate 17 which latches the contact 19 in the closed position with the contacts 24, 23, 19, 17 closed, and a spring 35 to ensure trip-free release of the bridging contact, the main compression spring 34 acting on the control member 28 has one end located in a hole 33 in the member 28 and its other end surrounding the adjusting screw 12 which secures the bimetallic strip 9 to the base 14 of the circuitbreaker. The spring 35 is a U-shaped wire spring. A push-button 4, the control rod 21 and the member 28 are formed in one piece of a plastics material, e.g. heat-resistant polyamide.
