摘要： A molded case circuit breaker includes an interlock which prevents the operating handle from being placed in the off position after the main contacts have been welded together. By preventing the operating handle from being placed in an off position during such a condition, the operating handle will indicate the correct status of the main contacts and the operator will be made aware that the main contacts are welded together.

摘要： A molded case circuit breaker is provided with a two piece cradle assembly having a cradle portion and a heat-treated portion. The heat-treated portion forms the latch and reset surfaces. The cradle portion is integrally formed from a pair of spaced apart cradle-shaped arms joined together by a connecting portion. The heat treated portion is securely fastened to the connecting portion to form the two piece cradle assembly. A hold down slidably carries a handle barrier with respect to the cover and closes a centrally located aperture in the cover for all handle positions. The handle barrier prevents arc products resulting from a separation of the main contacts from escaping through the centrally located aperture in the cover. Stops are provided in one or both directions to prevent misalignment of the handle barrier with respect to the operating handle. A cover interlock is also provided to prevent the cover from being removed when the circuit breaker is in an "on" position. The cover interlock can either be molded separately or integrallly molded with the handle barrier hold down.

摘要： Within a closing assembly that utilizes a ram assembly having a spring driven ram body, an energy dissipating spring seat assembly is provided. The ram body is mounted on a guide assembly having at least one pin. The guide assembly also includes a base plate and a stop plate. A ram assembly spring is disposed between the ram body and the base plate and is structured to bias the ram body toward the stop plate. The spring seat assembly includes a spring seat bracket and a spring seat. The spring seat is, preferably, a generally flat, plate-like leaf spring that is disposed between the ram assembly springs and the base plate of the ram body. The spring seat is sufficiently rigid so as to not deflect fully under the force created by the compressed ram assembly springs, but not so rigid as to resist deflecting under the force created when the ram body impacts the stop plate.

摘要： An improved lockable fastener that can be employed in a circuit breaker application includes a first member and a second member that are threadably cooperable with one another and a locking member that extends between the first and second members to resist loosening of the first and second members. The second member includes a threaded shank that is threadably received in a first threaded portion of a cavity formed in the first member. The locking member includes a threaded body and a taper, with the threaded body being threadably receivable in a second threaded portion of the first member, and with the taper being at least partially receivable in a receptacle formed in the shank of the second member. The receptacle defines a seat on the shank, and the taper engages the seat to deform at least a portion of the shank into engagement with a ledge that is interposed between the first and second threaded portions of the cavity.

摘要： A solenoid type magnetic trip assembly for a molded case circuit breaker includes an armature biased against an adjustable stop by a tension spring to set the initial gap for the magnetic trip, so that the spring bias remains constant for the full range of the initial gap. The armature includes an elongated armature element mounted by a frame to slide longitudinally along a pair of guide rails. The frame defines a trip surface axially aligned with the elongated armature element which engages a trip arm on a trip bar to trip the circuit breaker in response to a predetermined level of overcurrent. A bimetal providing a thermal trip function is cantilevered from a support spaced from the trip bar by the armature, but has a terminal portion at the free end projecting toward the trip bar and through which the elongated armature element of the armature extends. A radially enlarged slug on the free end of the elongated armature element of the armature is subjected to a magnetic force opposite to the force generated by load current tending to pull the armature into the solenoid coil. This opposing force increases as the initial gap increases, placing the slug closer to the magnetic frame, so that a greater range of trip currents can be selected despite limited room for armature travel. A gap in the magnetic frame prevents short circuiting the magnetic field where the few turns of a large gauge coil wire produce an unsymmetrical winding. A magnetic shield protects the bimetal from deformation during high current short circuits. A non-magnetic spring clip firmly retains the magnetic frame in a recess in the circuit breaker housing.
摘要翻译： 用于模制外壳断路器的螺线管型磁跳闸组件包括通过拉伸弹簧偏压抵靠可调节止动件的电枢，以设定磁跳闸的初始间隙，使得弹簧偏置在初始间隙的全部范围内保持恒定。 电枢包括由框架安装的细长电枢元件，以沿着一对导轨纵向滑动。 框架限定了与细长电枢元件轴向对准的跳闸表面，其接合跳闸杆上的跳闸臂，以响应于预定水平的过电流来跳闸断路器。 提供热脱扣功能的双金属从电枢与跳闸杆间隔开的支撑件悬臂，但是在自由端具有朝向跳闸杆突出的端子部分，衔铁的细长电枢元件通过该端子部延伸。 在电枢的细长电枢元件的自由端上的径向扩大的块状物受到与由负载电流产生的力相反的磁力，倾向于将电枢拉入螺线管线圈。 这种相反的力随着初始间隙的增加而增加，将芯块放置在更靠近磁性框架的位置，这样就可以选择更大范围的跳闸电流，尽管电枢行程有限。 磁性框架中的间隙防止了大规格线圈线的几匝产生不对称绕组的磁场的短路。 磁屏蔽保护双金属在高电流短路期间不会变形。 非磁性弹簧夹牢固地将磁性框架保持在断路器壳体的凹部中。

摘要： An adjusting knob assembly includes a knob member having a knob and an axially extending shaft. A support bracket has an aperture defined in part by a gapped ring section formed by a pair confronting arcuate fingers. The shaft and the aperture have complimentary, longitudinally extending, circumferentially distributed flat surfaces, which provide discrete angular positions for the shaft when the complimentary flat surfaces are in register. Preferably, the gap between the confronting fingers is sized, and the arcuate fingers have a compliance sufficient that the shaft may be passed laterally through the gap and snapped into the aperture. Any one of a plurality of interchangeable cam members can be press fit on to the end of the shaft.

摘要： This concerns a molded case circuit breaker having separable main contacts and an operating mechanism utilized to cause the separable main contacts to open and close. A trip unit is provided to actuate the operating mechanism in desirable circumstances. The trip unit is removable. In this case the trip unit is insertable into a trip unit region in the case of the circuit breaker from the top or end thereof. The trip unit is then joined to an internal electrical conductor by way of a bolt and an internally fixed nut. The bolt can be driven into the nut through the trip unit conductor and the internal conductor from a position external to the circuit breaker case. The trip unit can be inserted into the trip unit conductor from a point above the circuit breaker case or vise versa. The trip unit has a securement nut built into its case.

摘要： Rectangular bus bars alternatively engaged in either of a pair of crossed slots in a support block secured in a panel board are locked in place by a locking device incorporated in a cylindrical terminal portion of each bus bar. The locking device includes an expandable ring seated in a circumferential groove in the cylindrical terminal portion. A pair of actuating pins are urged radially outward in diametrically opposed bores to wedge the expandable ring against the support block, by a tapered screw threaded into a central longitudinal bore in the terminal portion of the bus bar.

摘要： A locking device is insertable into a cover opening adjacent to a handle of an electrical switch to occupy the space in the cover opening for resisting movement of the handle. The locking device has two pivotally connected members. The pivotal movement of the members creates a collapsed condition or an expanded condition for the locking device. The pivotal members have a transverse opening which are alignable relative to each other when the locking device is in its expanded condition. The locking device is inserted into the cover opening when the pivotal members are collapsed. In a first embodiment, a handle shroud member has an opening for receiving the handle and a second member has leg means along its base for engaging an undersurface around the cover opening when the locking device is in its expanded condition. In a second and a third embodiment, both pivotal members have leg means for engaging undersurfaces around the cover opening when the locking device is in its expanded condition. Once the apertures of the members are in alignment, a padlock is inserted therethrough for retaining the locking device in its expanded condition in the cover opening thereby resisting movement of the handle of the electrical switch.
