Wiegmann N412 Wall-Mount Enclosure

The Wiegmann N412 wall-mount enclosure provides a 24.0 in height by 20.0 in width by 12.0 in depth carbon steel housing rated NEMA 3R, 4, and 12 with an IP66 rating. A seamless polyurethane gasket and three-point keyed handle latch create a secure seal against dust, water, and oil. The ANSI 61 gray polyester powder finish protects the 14-gauge steel body in industrial environments. It includes mounting holes and a usable opening depth of 11.88 in.

Indoor Industrial Control Panels

This enclosure suits installers building indoor control panels or junction boxes that require a hinged solid cover and keyed access for security. The included 2NJ38 interior panel supports component mounting for automation or electrical distribution. Buyers needing a non-metallic body, a window cover for visual inspection, or a smaller footprint for tight wall spaces should look at other options. Outdoor installations requiring only NEMA 3R rain protection may find lighter alternatives.

Sustained Environmental Sealing

Under continuous exposure the poured-in-place polyurethane gasket maintains its compression set resistance, preserving the NEMA 4 and 12 seal against spraying water and circulating dust over long periods. The three-point latch distributes clamping force evenly around the door perimeter, preventing gasket fatigue that can occur with single-point closures. The 14-gauge carbon steel resists deflection when fully populated with mounted hardware. The polyester powder coating withstands prolonged UV and chemical contact without chalking.

Questions about this item

What size mounting hardware do I need for the 24.0 in H x 20.0 in W carbon steel enclosure?

The box has pre-drilled mounting holes for wall installation; use bolts or lag screws rated for the 14 ga steel and the weight of your internal components.

Will my existing 2NJ38 interior panel fit inside this N412-PTC series enclosure?

Yes, the 2NJ38 panel is listed as the designated interior panel for this model, so it mounts directly to the internal studs.

How can I verify the IP66 and NEMA 4 seals are intact after I close the 3 pt latch handle?

Inspect the seamless polyurethane poured-in-place gasket for full contact, turn the keyed handle until all three latches engage firmly, then confirm the door sits flush against the ANSI 61 grey finish.
