Door latch for electrical equipment enclosure |
摘要 |
A door latch for latching a door of an electrical equipment enclosure includes a latch body and a latch rod rotatable between locked and unlocked conditions. The latch rod includes a stem with a first end rotatably coupled to the latch body, an extension rod with a first end coupled to a second end of the stem, and a hook coupled to a second end of the extension rod. The extension rod is dimensioned to contact a portion of the electrical equipment enclosure when the latch rod is in the locked condition. The hook is separated from the portion of the electrical equipment enclosure by a clearance distance "x" during a quiescent condition within the electrical enclosure. The hook contacts the portion of the electrical equipment enclosure during a pressurized condition within the electrical equipment enclosure. The clearance distance "x" is selected to provide a clearance distance "y" between the door and the enclosure to allow pressurized gas to escape the enclosure during the pressurized condition.
