SEALED DOORS, ENCLOSURES, AND METHODS ADAPED FOR USE WITH ELECTRICAL ARC-PRONE COMPONENTS
First Claim
1. A sealed enclosure, comprising:
- a case configured to receive an arc-prone electrical component;
a face frame defining an opening;
a door configured to cover the opening;
a sealing surface on the face frame or on the door; and
one or more flaps having an sealing portion, the sealing portion being angled relative to the sealing surface, the one or more flaps being operational to flex from a disengaged position when not under pressure, to an engaged position in contact with the sealing surface when exposed to pressure inside the case during an arcing event.

Abstract
A sealed enclosure is disclosed. Sealed enclosure has a case configured to receive an arc-prone electrical component, a face frame defining an opening, a door configured to cover the opening, a sealing surface on the face frame or on the door, and one or more flaps having an sealing portion, the sealing portion being angled relative to the sealing surface, the one or more flaps being operational to flex from a disengaged position when not under pressure, to an engaged position in contact with the sealing surface when exposed to pressure inside the case during an arcing event. Sealed enclosure doors and methods of sealing an enclosure during an arcing event are also provided, as are other aspects.

16. A sealed enclosure, comprising:
-
a case configured to receive an arc-prone electrical component; a face frame on the case defining an opening, the face frame having a plurality of sealing surfaces; a door configured to cover the opening; and a plurality of flaps coupled to the door, one flap adjacent each edge of the door, the plurality of flaps each having an sealing portion being positioned relative to one of the sealing surfaces, the one or more flaps being operational to flex from a disengaged position when not under pressure, to an engaged position in contact with the sealing surfaces when exposed to pressure inside the case during an arcing event. - View Dependent Claims (17, 18, 19)

20. A sealed enclosure door, comprising:
-
a door configured to cover an opening of a case; and a plurality of flaps coupled to the door, one flap adjacent each edge of the door, the plurality of flaps each having an sealing portion, the one or more flaps being operational to flex from a disengaged position when not under pressure, to an engaged position in contact with sealing surfaces of an enclosure when exposed to pressure inside the case during an arcing event.

-
21. A method of sealing an enclosure during an arcing event, the method comprising:
-
providing a face frame on a case of the enclosure; providing a door on the case; providing a sealing surface on the door or the face frame; and sealing between the door and the face frame during the arcing event by flexing a flap into contact with the sealing surface responsive to pressure buildup in the enclosure due to the arcing event.
