Electrical enclosure for indoor wall mounting

The HOFFMAN ASE16X12X4 is a carbon steel enclosure rated NEMA 1 and IP 30 for indoor use. It measures 16.0 in height, 12.0 in width and 4.0 in depth with a solid screw-on cover. The grey ANSI 61 polyester powder finish resists corrosion in dry environments. Mounting holes allow direct wall installation for electrical junction or instrumentation housing.

Thermal and power characteristics in normal use

The solid carbon steel body dissipates heat from installed components through natural convection without forced airflow. No fans or active cooling are present so acoustic output is zero during operation. Power draw depends entirely on the devices mounted inside the enclosure rather than the box itself. The 12/14/16 gauge metal thickness provides structural rigidity while maintaining thermal mass.

Included mounting features and compliance

Pre-drilled mounting holes enable immediate wall attachment without separate brackets. The screw-latch cover secures with standard tools and maintains the NEMA 1 rating when closed. Certifications include CSA, cUL, IEC and UL Listed confirming compliance with North American and international safety standards. The A90P1 series designation identifies compatible accessories such as inner panels or mounting hardware sold separately.

Questions about this item

How do I mount the 16.0 in high carbon steel enclosure to the wall?

Use the pre-drilled mounting holes on the back of the 12/14/16 ga carbon steel body with appropriate fasteners for your wall type, ensuring the ANSI 61 gray polyester powder finish is not damaged during installation.

Will the screw-on solid cover gasket need replacement over time?

The solid cover uses a screw latch closure method; inspect the sealing surface periodically for compression set or damage to maintain the NEMA 1 and IP30 ratings in indoor environments.

At what point does the 4.0 in depth limit cable bending radius?

The 4.0 in internal depth restricts the minimum bending radius for larger conductors; plan wire routing to avoid sharp bends against the carbon steel walls or the screw-on cover interior.
