Abstract

1,088,698. Automatic circuit breakers. GEN. ERAL ELECTRIC CO. Oct. 19, 1965 [Oct. 22, 1964], No. 44183/65. Heading H2B. [Also in Division G1] The bimetal trip 26 of an automatic circuit breaker is attached to one end of a metal terminal strip 31 which is attached at an intermediate portion to the moulded case of the breaker, the strip 31 being deformable by a screw 40 to alter the position of the bimetal and having a portion of reduced cross-section adjacent a bend lying between the one end and the intermediate portion so as to substantially limit the deformation to the region of the bend. The cross-section may be reduced by an aperture 45 or by a notch (131A) (Fig. 6, not shown). The other end of the terminal strip 31 has extensions 38 engaging in apertures 39 in the moulded case to support the strip and carries a tubular wire connector 34. A further aperture 46 is cut in the strip 31 adjacent a second bend and rib 47 is formed in the intermediate portion.
