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 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 fusible disconnect switch devices includes dual sets of switch contacts to connect or disconnect a current path through an overcurrent protection fuse with reduced arcing severity. Faster acting and longer contact path switch mechanisms are described providing satisfactory switching of DC circuits without excessive electrical arcing in a reduced physical package size.

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.

Abstract: A disc member is for a Thomson coil actuator of an electrical switching apparatus. The Thomson coil actuator has at least one generally planar coil. The disc member includes at least one annular-shaped conductive member structured to be driven by the coil, and a structural support member directly coupled to the conductive member.

Abstract: A circuit interrupter system includes a vacuum circuit interrupter having a vacuum chamber that contains a fixed contact and a moveable contact. A non-conductive rod extends from the moveable contact. One or more Thomson coils are wound around the rod, and one or more armatures are connected to the rod. When a driver energizes one of the Thomson coils, a corresponding armature will be repelled from that Thomson coil and move the rod to open or close the contacts of the vacuum circuit interrupter. The system also may include a damper that provides an active damping force rod when the rod is moved to open and/or close the vacuum circuit interrupter.

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.
