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

摘要： An auxiliary magnetic trip unit for a circuit breaker arranged on the load strap of an industrial-rated circuit breaker to interrupt circuit current upon occurrence of a high-level short circuit fault. The magnetic trip unit employs a magnet yoke, an armature, a trip lever for interacting with a latching mechanism of a circuit breaker operating mechanism, and a lever arranged to restrain the armature from moving toward the magnet yoke and to release the armature in response to a predetermined level of pressurized gas. Thus providing an auxiliary magnetic trip unit for use with circuit breakers for selective short circuit overcurrent protection in an electrical distribution system with circuit breakers connected in series.

摘要： A current-limiting contact arrangement includes a conductor rail including a stationary contact and including two current loops extending at opposite sides of the conductor rail in respective planes parallel to a center plane of the contact arrangement. A contact arm including a movable contact which can be brought into and out of contact with the stationary contact is provided, the current loops extending in respective planes parallel to a center plane of the contact arrangement and along an entire opening travel of the movable contact. An arc control device including arc splitters and a cassette including a first part and a second part and an insulating material are also provided. The arc splitters are disposed in a positive-locking manner in an interior of the cassette, the contact arm and a part of the conductor rail including the stationary contact extending into the interior of the cassette, and the current loops being disposed in a positive-locking manner at outer walls of the cassette. An assembly of the cassette, the arc splitters and the conductor rail is received in a positive-locking manner by inner surfaces of a switching device enclosure.

摘要： A cassette assembly for rotary contact circuit breakers utilizing a first electrically insulative cassette half piece and a second electrically insulative cassette half piece which are arranged to mate with each other to form an enclosure. The electrically insulative cassette half pieces include improper installation rejection features for both the rotor and arc chute assemblies. The inner surface of a electrically insulative cassette half piece including a groove and recesses formed therein. A rotor is properly positioned within the electrically insulative cassette half piece by inserting a pin on the face of the rotor into the groove. An arc chute assembly is properly positioned within the electrically insulative cassette half piece by inserting a tab located on a side member of the arc chute assembly into a corresponding recess located in the electrically insulative cassette half piece.

摘要： An electromagnetic circuit breaker is provided with a pair of magnets on opposing sides of the contacts in the open position. A magnetic field generated by the magnets combines with the magnetic field generated by the electrical arc created upon opening of the contacts during an overcurrent condition sensed by the breaker. The combined magnetic fields deflect the arc current, shifting the arc current away from the contact points and lengthening the path of the arc, thereby increasing the voltage rating of the breaker, by decreasing the intensity of an associated arc current.

摘要： A current limiting device includes first and second contact members, each contact member having, at a first end, contacts defining a contact pair; a contacting pressure is applied to said contact pair; and a cylindrical insulator cylindrically surrounding the contacts when the contacts are closed. The device is arranged such that at least one of the first and second contact members is rotatably supported at a second end. Also, an electrical path is defined through which currents flow in substantial opposition to the first and second contact members and in opposite directions to each other. The first ends of the first and second contact members are positioned within the space defined by the cylindrical insulator in the closed contact state. The contact of at least one of the rotatably supported contact members is positioned outside of the space defined by the cylindrical insulator when the contacts are open.
