摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
