Electrical enclosures
A panel builder needs the door to close the same way every time, the seal to stay compressed, and the key system to match the site standard. That is three decisions: the closure type, the gasket, and the insert.
What to decide
Selection factors for electrical enclosures, in the order they usually come up.
Closure type
Single-panel doors up to roughly a metre are usually held by one or two quarter-turn cam locks. Full-height doors need a swing handle driving rods to roller catches top and bottom, so the leaf is pulled flat along its whole edge.
Insert and key standard
Sites standardise on an insert: 3 mm or 5 mm double-bit, 6 mm or 8 mm square, 8 mm or 9 mm triangle, or 6 mm Allen. Choose the lock to match the keys already on site, and order spare keys from Accessories.
Door thickness and cut-out
Each drawing shows the cut-out (for example the 25 × 100 mm rectangle used by the swing handles) and the sheet thickness range the body accepts. Check both before committing a laser-cut door.
Seal compression
A cam lock holds the door closed; a compression latch pulls it onto the gasket. Where dust or water is the concern, pair a compression latch with a pinchweld or foam gasket sized to the door-to-frame gap. The enclosure's ingress rating is a property of the finished, tested assembly, not of any one component.
Hinges
Leaf hinges with threaded studs fix blind from inside the door, so nothing is visible or removable from outside. Sizes from 40 × 40 mm to 60 × 136 mm.
Product families for electrical enclosures
Also from Accessories: Keys for every insert, dust caps, cam holders, document holders for the inside of the door, and 105 × 105 mm and 150 × 150 mm vents.
