摘要： An electromagnetic coil apparatus includes a ferrous coil frame having a first end and a second end opposite the first end. A coil assembly includes a conduit, a number of coils within the ferrous coil frame and being disposed on the conduit, and a ferrous plunger movable in the conduit. A first ferrous heel member is disposed proximate the first end of the ferrous coil frame. A second ferrous top plate member has an opening and is disposed proximate the second end of the ferrous coil frame. A magnetic flux enhancer is external to the conduit and is at least partially external to the ferrous coil frame. The magnetic flux enhancer includes a ferrous conduit coupled to the second ferrous top plate member and cooperates with the opening thereof to form a passageway. A portion of the ferrous plunger of the coil assembly passes through the passageway.

摘要： A trip unit includes a housing, a rotary plunger, and a pivotally mounted trip bar, which latches the plunger in an on position and releases the plunger to a tripped position. A first plunger portion is biased outside the housing in a tripped position by a spring mechanism. A pivotally mounted rotary trip lever includes an elastic arm. A second plunger portion is inside the housing in a reset position and engages the elastic arm. When a trip solenoid is energized, its linear plunger rotates the rotary trip lever, in order to engage and rotate the trip bar and release the rotary plunger. The rotary trip lever rotates in an opposite direction in response to the rotary plunger reset position and engages the trip solenoid linear plunger, in order to reset the same. The elastic arm flexes after the linear plunger is reset and accommodates overtravel of the rotary plunger.

摘要： A circuit breaker includes a housing, an operating mechanism and separable main contacts, and a rotatable crossbar which rotates to open and close the contacts. The crossbar interacts by way of a protrusion thereon with a rotatable, positive off-link. A handle mechanism is disposed in the housing and has a handle protruding from the housing which is normally movable from a closed to open disposition. However, if the operating mechanism has reacted in such a way as to open the separable main contacts but, in fact, they have not opened because, for example, they are welded shut, the protrusion on the crossbar will interact with the positive off-link and prevent the handle mechanism from moving to the opened position thus warning personnel that the contacts have not opened. There is also provided in association with the crossbar a cam which is spring loaded from the bottom against a portion of a cavity in a crossbar which interacts with a movable portion of the movable contact in such a manner as to latch it open when it has independently moved to an opened position relative to the rotatable crossbar. The cam rider reacts in such a way that it seals off or protects the aforementioned spring from gaseous arc products during the opening operation. There is provided on the trip mechanism a double pitch spring. The double pitch being such as to expand the range of the adjustment characteristic of the tripping mechanism.

摘要： A rotating display device displays a value in a variable viewing orientation. The value is received from an electrical apparatus, such as a circuit breaker, having a first port. The rotating display device includes a housing having a first side and a second side, a display disposed on the first side of the housing, a rotating assembly disposed on the second side, and a second port for receiving the value from the first port of the electrical apparatus. The second port communicates with the display and is coupled to the rotating assembly in order to permit the display to rotate. The rotating assembly permits the rotating display device to rotate in the plane of the surface of the circuit breaker on which it is mounted, thereby permitting the display to be quickly and accurately viewed and interpreted regardless of the orientation of the surface to which it is coupled.

摘要： A circuit breaker trip unit includes a housing and a rotary plunger pivotally mounted within the housing. The rotary plunger has an on position and a tripped position. A portion of the rotary plunger is pivoted outside of the housing in the tripped position. A trip bar is pivotally mounted within the housing and includes a first tab latching the rotary plunger in the first position and releasing the rotary plunger from the first position. The trip bar also includes a second tab. A trip actuator includes a solenoid and a rotary trip lever engaging the second tab of the trip bar, in order to pivot the trip bar and release the rotary plunger from the on position. A spring biases the trip bar, in order that the first tab latches the rotary plunger in the on position. A pair of springs biases the rotary plunger to the tripped position.

摘要： 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 circuit breaker has external terminals which are connectable with an external load and an external power supply. A collar is used to interconnect the circuit breaker terminals with the load and power supply. The terminal collar in this case is non-symmetrical. The non-symmetrical collar provides two functions: the first function is that the path of electrical continently between adjacent collars is enlarged for higher voltage applications because of the non-symmetrical nature of each collar; secondly, the circuit breaker case has a seat therein which has the same cross-section as the non-symmetrical collar, so that the collar can only be inserted therein in one cross-sectional orientation.
