    摘要: An electrical circuit interrupter comprising a housing with an operating mechanism disposed therein and including first and second separable main contacts disposed within the housing is taught. There is an electrically conducting first contact support which has a shape which substantially doubles back upon itself and which has parallel, spaced apart first and second legs forming a central region. An electrically insulating support member is supplied which is disposed in the central region and has a substantial portion outboard of the central region in a disposition to shield a portion of the contact support member. It also has a portion which captures the first contact support member. In addition, magnetic plates are disposed within the central region for cooperating with other closed loop magnetic plates outside of the support member for providing a slot motor action for the movable contact. An arc runner is provided which is trapped between the support member and the contact support conductor. All of this is disposed upon a protrusion in the housing of the circuit breaker and held in place by way of a securing device. Lastly, a mandrel is provided for supporting the aforementioned external magnetic plates. The mandrel is gas evolving so that under the influence of the heat of an electrical arc it evolves gas which helps to push the arc out and away from the opening contacts. The aforementioned gas propels the formed arc outwardly away from the contacts in an effort to cool and interrupt the arc.

    摘要: A molded case circuit breaker is provided with a toggle assembly having upper toggle links secured to U-shaped members of a cradle assembly with a hardened pin. The pin is formed with annular grooves disposed intermediate the ends forming a center sleeve portion and stop surfaces at each end. The center sleeve portion is slightly longer than the width of the U-shaped member to provide spacing between the upper toggle links and the U-shaped members. The upper toggle links are formed with U-shaped slots disposed at one end which are received in the annular grooves. The U-shaped slots formed at the other end of the toggle links are offset from the longitudinal axis of the toggle links and receive the pin. The upper toggle links are assembled such the offset U-shaped grooves are disposed in opposite directions to help secure the the assembly together. Tolerances in the components will allow a certain amount of axial movement of the upper toggle links and U-shaped members with respect to the pin, which can result in relatively large axial forces on the pin. Since the pin is formed from a hardened metal, the possibility of a failure of the pin is greatly reduced.

    摘要: A molded case circuit breaker includes a handle lock or locking mechanism for preventing unauthorized use of the circuit breaker. The locking mechanism includes a lock cover disposed over a manually engagable handle of the circuit breaker and a spring biased locking cylinder and spindle assembly disposed normally above the lock cover and movable along an elongated slot formed through the lock cover. The cylinder and spindle assembly is mechanically connected to the handle for movement in unison therewith. The elongated slot includes an enlarged locking portion that is located along the lock cover in a position corresponding to the OFF position of the handle and the OPEN position of the separable electrical contacts of the circuit breaker. An elongated cylinder of the cylinder and spindle assembly is receivable through the locking portion of the elongated slot and when retained therein prevents substantial movement of the handle from its OFF position.

    摘要: Insulative guide members secured to an end face of switching apparatus between power terminals route electrical leads from attachment devices mounted inside the molded housing of the switch which exit the housing above the power terminals down between the power terminals toward the rear face thereby providing physical separation and electrical isolation between these leads and the power terminals and conductors connected to them. The insulative guide members are secured to the molded housing by a tongue-and-groove connection. The insulative guide members also form interface barriers with increased, oversurface distance between adjacent power terminals and conductors which can be further increased by longitudinal ribs on the guide members. In another configuration, the guide members can be secured to the confronting end faces of adjacent switching apparatus to provide interface isolation and to route leads from auxiliary switches from adjacent a front face of the switches toward a rear face.

    摘要: A circuit breaker has an electrically conductive blow open latch which forms part of the power circuit so that only short flexible shunts are needed between the latch and trip mechanism. Load current can be conducted from the contact arm to the electrically conductive latch solely through the interface between the latch and the blow open camming surface on the contact arm, and/or through additional short flexible shunts between the latch and the contact arm, preferably adjacent the pivot of the contact arm.

    摘要: A molded case circuit breaker includes a movable upper electrical contact member having an end portion with an arcuate cam surface formed thereon for engaging an exposed spherical surface of a spring-loaded ball that is disposed in a pocket provided in a rotatable cross-bar of the operating mechanism of the circuit breaker. A compression spring is also disposed in the pocket between the cross-bar and the ball to supply sufficient biasing force to the end portion of the movable upper electrical contact member to enable the upper electrical contact member to move in unison with the cross-bar during normal operation of the breaker. Upon the occurrence of a high level short circuit or fault current of sufficient magnitude, the upper electrical contact member rotates and the arcuate cam surface thereof moves against the exposed surface of the then stationary spring-loaded ball. The arcuate cam surface of the end portion is configured to provide a decreased biasing force as the upper electrical contact member rotates to its BLOWN-OPEN position. A detent or groove is formed along the arcuate cam surface of the end portion of the contact member for receiving the exposed surface of the spring-loaded ball to retain the movable upper electrical contact member in a BLOWN-OPEN position, thereby minimizing the possibility of contact restrike.

    摘要: A molded case circuit breaker is provided with rubber stop assemblies disposed between the contact assemblies adjacent the outside poles and the cover portion of the housing. The rubber stop assemblies are disposed such that they prevent the contact assemblies from damaging the cover. The stop assemblies include a dual purpose U-shaped bracket having two parallel sets of arms. One set of arms is provided with aligned apertures at the free ends for receiving a pin which defines a pivot point for the crossbar assembly. The other set of arms is also provided with aligned apertures at the free end for receiving a metal pin for carrying a cylindrical shock absorber assembly. The shock absorber assembly is mounted adjacent outside poles above the contact carrier but spaced away from the inside of the cover of the circuit breaker. Thus, when the contact arm is opened, it will stop against the shock absorber and not damage the circuit breaker cover. The center pole is provided with an adjacent shock absorber, mounted between a pair of spaced-apart sideplates, vertically disposed and secured to the frame of the circuit breaker. The center pole shock absorber is spaced away from the operating mechanism to prevent the center pole contact assembly from contacting it.
