摘要： A return spring mechanism (302) is arranged to operate with a circuit breaker operating mechanism (32) during a trip condition. The circuit breaker operating mechanism (32) is movable between a tripped position, a reset position, an off position and an on position. The return spring mechanism (302) is attached to the exterior of the circuit breaker frame (86) and includes a return spring (288) with a fixed end (304) attached to the frame (86). When the circuit breaker (20) is tripped, the return spring mechanism (302) operates to provide an additional force to the handle yoke (88). The additional force applied by the return spring (288) is predetermined to position the handle yoke (88) intermediate to the handle yoke (88) positions when the circuit breaker (20) is off and on. Thus, the movement of the handle yoke (88) to the intermediate position provides clear indication that the circuit breaker (20) is in the tripped condition.

摘要： A cassette assembly for rotary contact circuit breakers utilizing a first electrically insulative cassette half piece (14) and a second electrically insulative cassette half piece (60) which are arranged to mate with each other to form an enclosure. The electrically insulative cassette half pieces (14, 60) include improper installation rejection features for both the rotor (37) and arc chute assemblies (20, 22). The inner surface (52, 62) of an electrically insulative cassette half piece (14, 60) including a groove (58) and recesses (54, 56, 64, 66) formed therein. A rotor (37) is properly positioned within the electrically insulative cassette half piece (14, 60) by inserting a pin (114) on the face (19) of the rotor (37) into the groove (58). An arc chute assembly (20, 22) is properly positioned within the electrically insulative cassette half piece (14, 60) by inserting a tab (80) located on a side member (70, 72, 82, 84) of the arc chute assembly (20, 22) into a corresponding recess (54, 56, 64, 66) located in the electrically insulative cassette half piece (14, 60).

摘要： A circuit breaker assembly (10) includes first and second rotary contact assemblies (12) mountable to a base member, a circuit breaker operating mechanism (13) mounted to the first rotary contact assembly (12), and a trip bar (54) in mechanical communication with the first rotary contact assembly (12) and the circuit breaker operating mechanism (13). The rotary contact assemblies (12) each include rotors (34) rotatable about axes therethrough and movable contact arms (30) pivotally mounted within the rotors (34). The circuit breaker operating mechanism (13) serves to position the rotors (34) to separate movable contacts (26) thereon from fixed contacts (24). A trip override device includes spring links (36) operably connected via springs to each of the rotors (34) of the rotary contact assemblies (12) and the trip bar (54). The trip bar (54) comprises trip levers (52) protruding radially therefrom and being in mechanical communication with the rotary contact assemblies (12).

摘要： A termination connector (40, 90) for a circuit breaker (10, 130) is disclosed. The termination connector (40, 90) preferably includes a plurality of single pole screw receiving members (42, 94) integrally attached by a molded housing (44, 92) for unitary attachment to a line or load end (22, 20) of a circuit breaker (10, 130) to assist in holding a nut (60) or nut plate (170) adjacent each screw hole (34) in the circuit breaker's terminal straps (32). The molded housing (44, 92) preferably includes a line of perforations (82) between each single pole screw receiving member (42, 94) so that the correct number of single pole screw receiving members (42, 94) can be retained and the others can be knocked off along the line of perforations (82). Provisions are disclosed for adaption of the connector (40, 90) to metric or English standard nut hardware. In addition, the termination connector (40, 90) and circuit breaker (10, 130) are provided with mating attachment devices (70, 72, 74, 76, 120, 140, 132, 150) for providing a simple yet secure connection.

摘要： An operating mechanism (38) controls and trips a separable contact structure (56) arranged in a protected circuit. The mechanism (38) includes a frame (86), a drive member (88) pivotally coupled to the frame (86), a spring (96) pivotally connecting the drive member (88) to a drive connector (235), an upper link (174) pivotally seated on the drive connector (235), a lower link member (194) pivotally coupled to the drive connector (235), a crank member (208) pivotally coupled to the lower link member (194) for interfacing the separable contact structure (56), and a cradle member (106) pivotally secured to the frame (86) and pivotally securing the upper link (174). The cradle member (106) is configured for being releasably engaged by a latch assembly (126, 138), which is displaced upon occurrence of a predetermined condition in the circuit such as a trip condition. The mechanism (38) is movable between a tripped position, a reset position, an off position, and an on position. Spacers (189, 192, 196, or 234) are operatively positioned between movable members (106, 174, 194, 208), and protrusions (224, 226 or 228) are operatively formed on the enclosure (32, 34 or 36) of the contact structure (56). The spacers (189, 192, 196, or 234) and protrusions (224, 226 or 228) serve to widen the stance of the operating mechanism for force distribution purposes, and also to minimize friction between movable components (106, 174, 194, 208).
