US Classification:

361608, 200306, 218155, 361605, 361611, 361673

Abstract:

A seal assembly for an electrical enclosure having a draw-out circuit breaker and a number of conductors is provided having a movable first seal member and a movable second seal member. The circuit breaker includes a protruding nose portion that is engaged by the first and second seal members in a manner that sealingly engages the nose portion. The arrangement of the first and second seal members and the nose portion provides for the sealing engagement to be maintained when the circuit breaker is moved from a first position in which the circuit breaker is not electrically connected to the number of conductors and a second position in which the circuit breaker is electrically connected to the number of conductors.

International Classification:

H05K 7/00

US Classification:

361819, 361801, 361755

Abstract:

A mounting assembly is provided for an electrical switching apparatus, such as a circuit breaker. The circuit breaker includes a housing having an exterior and an interior, separable contacts disposed in the interior, and an operating mechanism structured to open and closed the separable contacts. The exterior of the housing includes a recess. The mounting assembly includes a bracket assembly having at least one bracket, an expansion member coupled to a corresponding one of the at least one bracket and being disposed within the recess on the exterior of the housing, and an actuator movably coupled to the expansion member. The actuator is movable between an actuated position corresponding to the expansion member expanding outwardly within the recess to secure the mounting assembly to the circuit breaker, and an unactuated position corresponding to the expansion member not being expanded and the mounting assembly being removable from the circuit breaker.

US Classification:

361605

Abstract:

A panel assembly for an electrical enclosure has a fixed mounting portion and a movable panel portion. The electrical enclosure has an interior substantially sealed from an exterior except at a number of apertures. The panel assembly includes a mounting portion coupled to the enclosure and a panel portion generally disposed over a corresponding one of the number of apertures. The panel portion is movable in a first direction from a first position to a second position by gas formed from an arcing event within the electrical enclosure passing outward through the corresponding aperture. The panel portion is constrained from movement in an opposite second direction due to a portion of the electrical enclosure.

International Classification:

H01H 33/12
H01H 71/12

Abstract:

An arc quenching device creates a fault on a bus. A lockout mechanism of a circuit breaker feeding the bus is responsively actuated. Actuating the lockout mechanism may include releasing a spring-loaded mechanism mounted on a cassette that holds the circuit breaker to cause the mechanism to engage a lockout member of the circuit breaker.

Assignee:

EATON INTELLIGENT POWER LIMITED - Dublin

International Classification:

G02B 6/38

Abstract:

An apparatus includes first and second components. A track supports one of the components for movement toward the other of the components. A first connector is mounted on the first component. The first connector retains an end portion of a first fiber optic cable, and has a first alignment portion. A second connector retains an end portion of a second fiber optic cable, and has a second alignment portion. The second alignment portion guides the second fiber optic cable radially into coaxial alignment with the first fiber optic cable upon movement of the first alignment portion against the second alignment portion. A floating mount device supports the second connector on the second component for guided movement radially relative to the second component upon movement of the first alignment portion against the second alignment portion.
