摘要： A heater assembly is provided for an electrical switching apparatus. The heater assembly includes a heater element and an elongated bimetal. The heater element includes first and second ends, an intermediate portion disposed therebetween and an aperture disposed proximate the first end. The elongated bimetal includes opposing first and second ends, and is movable between first and second positions corresponding respectively to the separable contacts of the electrical switching apparatus being closeable, and to the first end of the elongated bimetal cooperating with a trip bar to cause an operating mechanism to open the separable contacts. The second end of the elongated bimetal is coupled to the intermediate portion of the heater element. When the elongated bimetal is disposed in the first position, the first end of the elongated bimetal extends beyond the upper surface of the first end of the heater element into the aperture of the heater element.

摘要： A flexible conductive element is provided for the conductor assembly of an electrical switching apparatus. The conductor assembly includes a load conductor, a movable contact assembly including a number of movable contact arms, movable electrical contacts mounted on the movable contact arms, and a plurality of flexible conductive elements. Each flexible conductive element includes a first end electrically connected to the load conductor, a second end electrically connected to a corresponding one of the movable contact arms of the movable contact assembly, and a plurality of bends between the first end and the second end. A first one of the bends is in a first direction and at least a second one of the bends is in a second direction which is generally opposite the first direction, in order that the flexible element is generally S-shaped. A conductor assembly and an electrical switching apparatus are also disclosed.

摘要： A ground fault circuit breaker has line and neutral bus bars extending through the center apertures of two laterally spaced toroidal coils to form the primaries of ground fault sensing transformers. The bus bars have flat center sections extending between the two coils parallel to the coil end faces and offset laterally by flat laterally extending legs at each end which are bent transverse to the end faces of the coils and extend through the coil apertures in flat confronting relation. The leg on one end of the neutral bus bar has a terminal portion bent into a plane parallel to the center section with a crimp at the end for attachment to a neutral pigtail.
