Abstract

838,462. Automatic circuit-breakers. BUSCH - JAEGER DURENER METALLWERKE A.G. Oct. 16, 1957 [Oct. 17, 1956], No. 32371/57. Addition to 789,326. Class 38 (5). In a modification of the circuit-breaker of the parent Specification, the recessed insulating blocks form an inverted T - shaped member, an arcquenching chamber being provided between the horizontal part 2 of the member and a side wall of the casing 3. This chamber communicates with expansion chambers 6, 7 disposed between the vertical part 1 of the member and the end walls of the casing 3. Ribs 13 may be provided in the arc quenching chamber.
