摘要： A gas segregator barrier is for quenching, segregating and controllably directing ionized gases discharged from a pair of spaced-apart circuit breakers double-branch mounted within a panelboard assembly. The spaced-apart circuit breakers include corresponding pairs of opposing poles, and a housing with exhaust vent openings for discharging ionized gases developed from an electrical fault. The gas segregator barrier includes at least substantially parallel segregator fins divided into first and second portions by a transverse dividing member. Baffles in the transverse dividing member quench the ionized gases and provide fluid communication between exhaust channels formed between the segregator fins of the first portion, and gas ducts disposed between the segregator fins of the second portion. The gas ducts include one or more lateral members structured to controllably direct the discharged ionized gases.

摘要： A gas discharge filter is for cooling ionized gases discharged from a circuit breaker. The circuit breaker includes separable contacts electrically connected in series between line and load terminals, a housing, an arc chamber within the housing structured to extinguish an arc between the separable contacts when opened, and an exhaust vent in the housing for discharging ionized gases developed from the arc. The gas discharge filter includes a heat exchanger for reducing the temperature of the discharged ionized gases, and a supporting member to secure the heat exchanger outside the housing and proximate the exhaust vent opening in the exhaust path for the discharged ionized gases. The discharge filter cools the discharged ionized gases as they pass through and around the heat exchanger thus reducing the likelihood of electrical faults associated therewith.
摘要翻译：气体放电过滤器用于冷却从断路器排出的电离气体。断路器包括在线路和负载端子之间串联电连接的可分离触点，壳体，壳体内的电弧室，其被构造成在打开时消除可分离触点之间的电弧;以及壳体中的排气口，用于将从电弧。气体放电过滤器包括用于降低排放的离子化气体的温度的热交换器，以及用于将热交换器固定在外壳外部并且靠近排气路径中排出的排气口的排出的离子化气体的支撑构件。排放过滤器在排出的离子化气体通过并绕过热交换器时冷却，从而减少与其相关联的电气故障的可能性。

摘要： A cover assembly controls access to the interior of an electrical enclosure. The electrical enclosure includes a housing having a panel and a plurality of walls extending from the panel to define an opening. The cover assembly includes a door-in-door assembly with first and second hinged doors and a concealed mounting mechanism. The concealed mounting mechanism secures the door-in-door assembly to the housing without requiring a separate securing mechanism. The first hinged door pivots open to access the housing without requiring the first door to be entirely removed. The second hinged door is smaller and thus provides convenient access through a cut-out portion of the larger first door. Access may be further controlled via a locking mechanism for locking the second door in a closed position within the first door.
摘要翻译：盖组件控制进入电气外壳的内部。电气外壳包括具有面板和从面板延伸以限定开口的多个壁的壳体。盖组件包括门内组件，其具有第一和第二铰链门和隐蔽的安装机构。隐藏的安装机构将门内组件固定到外壳上，而不需要单独的固定机构。第一铰链门枢转打开以进入外壳，而不需要将第一个门完全拆除。第二铰链门较小，因此通过较大的第一门的切口部分方便地进入。可以通过用于将第二门锁定在第一门内的关闭位置的锁定机构进一步控制通路。

摘要： An apparatus for interlocking horizontally adjacent first and second circuit breakers and preventing the circuit breakers from simultaneously being in a closed operating position. The circuit breakers each have a pivotable actuating handle movable between a closed position which is proximal to the other circuit breaker, and a open position which is distal to the other circuit breaker. A housing lies between the first and second circuit breakers and an interlock bar is slidably retained in the housing. In operation, the interlock bar is slidable between a first position where the interlock bar prevents the first circuit breaker handle from pivoting into the closed position and a second position where the interlock bar prevents the second circuit breaker handle from pivoting into the closed position. If the interlock bar is in the first position and the handle of the second circuit breaker is in the closed position, the handle of the second circuit breaker prevents the interlock bar from being moved into the second position. To move the interlock bar into the second position, the user must move the handle of the second circuit breaker into the open position. Once the handle of the second circuit breaker is in the open position, the interlock bar can be moved into the second position and the handle of the first circuit breaker may be closed. While the interlock bar is in the second position and the handle of the first circuit breaker is in the closed position, the handle of the first circuit breaker prevents the interlock bar from being moved into the first position.
摘要翻译：一种用于互锁水平相邻的第一和第二断路器并防止断路器同时处于关闭操作位置的装置。断路器各自具有可枢转的致动手柄，其可在靠近另一个断路器的关闭位置和远离另一个断路器的打开位置之间移动。壳体位于第一和第二断路器之间，并且互锁条可滑动地保持在壳体中。在操作中，联动杆可以在第一位置和第二位置之间滑动，在第一位置处，互锁杆防止第一断路器手柄枢转到关闭位置，而第二位置，联锁杆防止第二断路器手柄枢转到关闭位置。如果联锁杆处于第一位置并且第二断路器的手柄处于关闭位置，则第二断路器的手柄防止互锁杆移动到第二位置。为了将互锁杆移动到第二位置，用户必须将第二断路器的手柄移动到打开位置。一旦第二断路器的把手处于打开位置，则互锁杆可以移动到第二位置，并且第一断路器的手柄可能被关闭。当互锁杆处于第二位置并且第一断路器的手柄处于关闭位置时，第一断路器的手柄防止互锁杆移动到第一位置。
