Abstract

1,094,377. Automatic circuit breakers. SQUARE D CO. June 1, 1965 [June 16, 1964], No. 23201/65. Heading H2B. The subject matter of this Specification is identical with that of Specifications 1,094,378, 1,094,379 and 1,094,380 but the claims relate to the actuating mechanism. The contact arms are operated by a common bar 40 mounted by arms 92 on the contact pivot 82, the contact arms 43 being biased against it by springs 93. The arms 92 are coupled through a shaft 10 to one end of a toggle linkage which is operated between open and closed positions by a handle 24 and an overcentre tension spring 77. The other end of the toggle linkage is pivoted to a lever 96 normally latched by a pivoted blade 118 itself latched by a plate on the common trip bar 39. The shaft 109 is provided with a hexagonal head engaging in a hexagonal hole in one arm 92 and with an eccentric portion 111 engaging in a sleeve 108 carried by the lower links of the toggle. The shaft 109 can thus be inserted in any one of six positions allowing the relative positions the linkage and contact arms to be set to overcome manufacturing tolerances. The handle 24 is sealed to the casing by an insulating plate 28 slidable to a limited extent relative to the handle.
