An improved circuit breaker includes an inertial time delay mechanism that permits a self-powered trip unit to become fully operational before inputting into the trip unit a signal indicating a change in the state of the circuit breaker. The time delay mechanism includes an inertia member, a first spring, and a second spring, and is activated upon the rotation of a lay shaft of an operating mechanism of the circuit breaker. The first spring extends between the inertia member and a housing of the circuit breaker and biases the inertia member from an initial position toward a terminal position. The second spring extends between the lay shaft and the inertia member and biases the inertia member toward the initial position when the circuit breaker is in an OFF condition. The combined action of the first and second springs on the inertia member provides a time delay using a relatively small inertial mass.

The present invention provides a motor control cam having a relief channel adjacent to the switch lever notch. The relief channel extends generally circumferentially from said switch lever notch under the second, wide diameter portion of the cam surface. In this configuration, when the switch lever is in the switch lever notch and a counter rotation of the cam occurs, the switch lever enters the relief channel and does not impact against the cam. As such, the switch lever is not damaged or moved out of adjustment by a counter rotation of the cam.

A vacuum circuit breaker includes a line terminal, a load terminal and a vacuum interrupter having a vacuum envelope containing a fixed contact assembly and a moveable contact assembly moveable between closed and open circuit positions. The fixed contact assembly is electrically interconnected with the line terminal and the moveable contact assembly is electrically connected to the load terminal. An operating mechanism moves the moveable contact assembly between the closed and open circuit positions. An auxiliary contact indicates one of the open or closed circuit positions. An electro-optical voltage sensor determines a voltage difference between the line and load terminals, or the shield and one of the line and load terminals. A circuit determines no leakage or loss of vacuum of the vacuum envelope when the vacuum switch is intended to be in the open circuit position and when the voltage difference is greater than a predetermined amount.

A solenoid assembly for a circuit breaker having a clapper with an increased mass is provided. The mass, preferably at least one non-ferrous slug, increases the mass of the clapper so that the solenoid response time is slowed. That is, the added mass creates an inertial delay that slows the solenoid clapper as the clapper moves between the first position and the second position. Preferably, the delay is between 48 ms and 60 ms, and more preferably 50 ms. The clapper having a non-ferrous slug may also be incorporated into existing circuit breakers by, for example, coupling the non-ferrous slug to the preexisting clapper, or replacing the clapper with a clapper assembly having at least one non-ferrous slug thereon.

A stored energy assembly is provided for an electrical switching apparatus, such as a circuit breaker. The stored energy assembly includes a mount removably coupled to the circuit breaker housing. A stored energy mechanism, such as a spring, is coupled to the mount and is movable among charged and discharged positions. An actuating element is cooperable with the gears of a gear assembly in order to move among first and second positions corresponding to the spring being disposed in the charged and discharged positions, respectively. A manual charging mechanism and an automatic charging mechanism are coupled to the gear assembly, and move the gears, in order to move the actuating element and charge the spring. The spring, the actuating element, the gear assembly, and the charging mechanisms are coupled to the mount, thereby forming a sub-assembly. The sub-assembly is removeably coupled to the circuit breaker housing.

A non-homogeneous cam includes an eccentric disk having side surfaces with an opening therethrough, and a cam surface disposed between the side surfaces. A first radius extending from a point within the opening to a number of first portions of the cam surface and second radii extending from the point to second portions of the cam surface define the cam surface. The first radius is greater than each of the second radii. The cam surface includes a first cam surface generally having the first radius and a second cam surface having a plurality of the second radii. The first and second cam surfaces define an angle of less than 90 degrees. The eccentric disk is generally made of a first material having a first strength. A portion of the eccentric disk between the first and second cam surfaces is made of a different second material having a greater second strength.

Heat sinks are placed on the contact stems of a vacuum interrupter between the vacuum bottle and junctions with the terminal conductors to lower the temperature of these junctions. The heat sinks are formed by a stack of thin laminations having central openings with inwardly directed tabs which bite into and secure the laminations to the stems. The laminations have aligned slots forming axial passages for cooling air. Preferably, the slots are enclosed to eliminate sharp peripheral edges to reduce the potential for flash over. In one embodiment, the slots are not formed by removing material but by bending it out of the plane of the lamination to maximize heat radiating surface area and to generate turbulent cooling air flow for increased cooling efficiency. An axially extending peripheral lip can provide axial spacing between laminations.

An auxiliary switch operator for a circuit breaker operates auxiliary contacts between open and closed positions. The auxiliary switch operator includes a hub which is biased to follow a pole shaft of the circuit breaker and follow the pole shaft when it rotates in a first direction to close separable contacts of the circuit breaker. A first spring mechanism biases the hub to follow the pole shaft when the pole shaft rotates in the first direction. When the pole shaft rotates in the first direction, an arm of the hub engages a rotatable shaft to drive an operating lever and operate the auxiliary contacts to the closed position. When the pole shaft rotates in the second direction, another arm of the hub recharges the first spring mechanism. A second spring mechanism biases the rotatable shaft and the operating lever toward a position corresponding to the open position of the auxiliary contacts when the pole shaft rotates in the second direction.
