Abstract
1,094,379. Automatic circuit breakers. SQUARE D CO. June 1, 1965 [June 16, 1964], No. 18702/67. Divided out of 1,094,377. Heading H2B. The subject matter of this Specification is identical with that of Specifications 1,094,377 1,094,378 and 1,094,380 but the claims relate to the venting of the arc chambers. Each pole of the circuit breaker is provided with an arc shoot comprising a plurality of ferrous metal plates 60 mounted between vulcanized fibreboards 61. Further fibreboards 62, 64, 66 complete the shoot, vents 63, 65 being provided in boards 62 and 64. In addition the shoot communicates through a passage 72 with a channel 68 extending across the base of the housing and covered by a plate 69. The channel 68 is vented, at each end, through the sides of the casing and is shaped at (75) (Fig. 2, not shown) to direct gases from the centre pole to both ends.
