摘要： A motor operator unit for an electrical switch is pivotally mounted on a bracket to swing between a closed, operative position in which an actuator in the motor operator unit engages the switch handle for electrical operation of the switch handle and an open position in which the switch handle is freely accessible for direct manual operation. The compliant actuator which is translated by a motor driven threaded shaft overtravels at each end of its reciprocal path after actuation of the switch handle to toggle a single power switch which determines both direction and shutoff of motor operation. A lockout plate mechanically prevents electrical and manual operation of the switch handle and carries an interlock switch which only enables motor operation when the motor operator unit is in the operative position and not locked out. The actuator is configured to prevent full rotation of the motor operator to the operative position, if the position of the actuator, which is virtually identified by indicators, does not correspond to handle position.

摘要： A laminated contact assembly formed from a plurality of contact arm subassemblies includes a contact arm portion, for carrying a movable main or arcing contact, and a stationary conductor portion. A flexible shunt, form wound from a flat electrical conductor, is used to connect the contact arm portion to the stationary conductor portion. The flexible shunt is formed into a V-shape defining two depending legs. The free ends of the shunt defining bulb portions are inserted into keyholes formed in the contact arm portion and the stationary conductor portion. A pin is inserted into a central portion of the bulb portion to exert radially outward forces against the interior surface of the keyhole to increase the contact force between the bulb portions and the keyholes to form joints having a lower electrical resistance. The pin may be inserted into the central portion of the bulb portion by orbital riveting.

摘要： An operating mechanism for an enclosure-mounted circuit breaker includes a slider for engaging the circuit breaker handle; a shaft-driven pivot for moving the slider between the handle on, off and reset positions; a holder for holding the slider in its reset position; a base plate for supporting the pivot and the slider; and a door-mounted rotary handle for rotating the shaft and operating the pivot. The rotary handle may engage the shaft in the on and off positions, and may be detached from the shaft in the reset position. The pivot may include a first pivot arm having a first cam surface for holding the slider in its reset position. A second cam surface on a second pivot arm may engage a first slider surface from off to on; a second slider surface from on to off, from off toward reset, and to resist reset to off; and an oblique slider surface when adjacent reset. The second cam surface may disengage the oblique surface at reset. Alternatively, the slider may include a notch and the base plate may include a latch for engaging the notch. The pivot may include a single pivot arm having a cam surface which engages a slider surface from off to on; an oblique slider surface from on to off, and from off to reset in order to engage the notch and the latch; and another oblique surface to disengage the notch and the latch from reset to off. The slider may include an oblique shoulder for moving the handle from on to off and from off to reset, for resisting the handle force from reset to off, and for using the handle force to engage the notch and the latch in the reset position in order to substantially decouple the handle force from the rotary handle.

摘要： An electrical switching apparatus interface assembly provides remote actuation of the operating handle of a circuit breaker. The interface assembly includes the circuit breaker, a second switching apparatus, such as an actuating handle disposed in a remote location from the circuit breaker, a connector and an operating handle attachment including a handle-engaging segment for securely engaging the circuit breaker operating handle and an interfacing segment for receiving the connector. The actuating handle is operable between ON and OFF positions corresponding to ON and OFF positions, respectively, of the circuit breaker operating handle. The connector interfaces or links the circuit breaker to the actuating handle. In this manner, when the actuating handle is moved from the ON or OFF position, the connector moves the circuit breaker operating handle in a likewise manner.

摘要： A locking attachment is for a circuit breaker. The circuit breaker includes a housing enclosing separable contacts and an operating mechanism, an elongated operating member with a handle that operates to open and close the separable contacts, and an opening in the housing through which the elongated operating member protrudes. The opening has first and second ends corresponding to “on” and “off” circuit breaker positions, respectively. The locking attachment includes a locking member having a first end having a compressive segment with opposed portions for compressively capturing the operating member. The second end of the locking member is structured to engage the housing of the circuit breaker at one of the first and second ends of the opening in the housing, thereby locking the circuit breaker in either the “on” or “off” position.

摘要： The helical contact compression springs of a circuit breaker are preassembled in a contact clip for easier assembly of the circuit breaker. The bottom wall of an elongated trough formed by the clip is pierced by holes forming cylindrical protrusions extending into the trough. The clip is placed over the springs supported in a row in a fixture. A die head presses on the spring clip to compress all the springs and then simultaneously insert punches into the holes in the clip to expand the protrusions and secure the springs to the clip. The fixture includes a slide mounted on guides for movement between a loading position and an operating position under the die head. A support block is pivoted on the slide to present one of two sets of spring recesses for circuit breakers having different current ratings with the slide in the loading position.
