Abstract: Cradle-assist assemblies attached to the breaker cradle housing and/or base or residing at least partially in the breaker cradle housing and/or base include at least one actuator configured to laterally translate the at least one right and the at least one left lock members from the extended lock position to the retracted unlocked position in response to input from a user. The at least one actuator and/or transverse member(s) can be held in a defined position so that the lock members of the cradle can be locked in the respective retracted or extended positions until the cradle assist (internal) lock is manually or automatically released.

Abstract: A electric locker differential assembly includes a first and second side gear. A pinion gear set is disposed between the first side gear and the second side gears. An engagement shaft includes flyweights disposed on the engagement shaft which are moveable between retracted and extended positions to lock and unlock the differential assembly. A lockout shaft includes a pawl disposed thereon. An electrical adjustment mechanism includes an actuator operably connected with an adjustment nut or rod. An electrical adjustment biasing spring includes a first leg retained by the adjustment nut and a second leg connected with the pawl wherein movement of the adjustment nut by the actuator varies a biasing force applied to the pawl.

IPC: H01H3/60

Abstract: A damping and latching mechanism for a Thomson coil-based actuator used to open and close the separable contacts of circuit interrupters in circuit breakers uses magnetorheological fluid to actively control the damping of opening and closing strokes in a circuit breaker in order to decrease wear and tear on components that can result from contact-based damping mechanisms and to maintain the open and closed states of separable contacts in the circuit breaker.

Abstract: A circuit interrupter includes separable contacts, a drive shaft coupled to the separable contacts and structured to move to open and close the separable contacts, a tapered drive shaft section coupled to the drive shaft and having tapered sides, and a friction assembly. The friction assembly includes a friction device structured to interact with the tapered sides of the tapered drive shaft, an armature coupled to the friction device, and a biasing member structured to bias the friction device and armature toward the tapered drive shaft section.

Abstract: A vacuum chamber contact assembly includes a vacuum housing assembly, a conductor assembly, and an operating mechanism. The vacuum housing assembly defines a sealed enclosed space. The conductor assembly includes a first stationary conductor assembly, a second stationary conductor assembly, and a movable conductor assembly. The operating mechanism includes a number of stationary components, a number of movable components and an actuator/latch assembly. The movable conductor assembly and the operating mechanism movable components are disposed entirely within the vacuum housing assembly enclosed space. The actuator/latch assembly includes an open, first latch unit and a close, second latch unit. The actuator/latch assembly is structured to maintain the movable conductor assembly in both the first position and the second position.

Abstract: A medium or low voltage circuit interrupter includes a housing with a first end cap, a second end cap that comprises a radial bellows, and one or more insulating sidewalls that extends from the first end cap to the second end cap. The end caps and one or more sidewalls provide a vacuum chamber. A fixed contact that extends through an opening of the first end cap and into the vacuum chamber. A moveable contact that extends through an opening of the second end cap and into the vacuum chamber. Multiple such interrupters may be electrically connected in series, positioned a single plane, and actuated by a single actuator.

Abstract: For a hybrid circuit interrupter that includes a secondary actuator disposed in series with a primary actuator, with the primary actuator used for opening the switch at ultra-fast speeds and the secondary actuator used for opening the switch at normal speeds, a performance monitoring system is disclosed. The monitoring system can use either an optical sensor or position sensitive device (PSD) to detect movement of the primary actuator. The optical sensor is coupled to the circuit interrupter housing, and a distance detection means is disposed within the secondary actuator in a manner that enables the optical sensor to detect the movement of a reference surface on the moving assembly of the primary actuator. The PSD is positioned to face a thru-hole formed in a drive shaft of the circuit interrupter, and to sense a change in position of light emitted through the thru-hole during an opening stroke.
