Hoffman NEMA 12 vs Unity NEMA 1 Control Enclosure: Pick by Size and Price

Compare the Hoffman A302408LP 30x24x8 NEMA 12 industrial enclosure to the Unity 12x12x6 NEMA 1 steel box by price, size, and protection, then decide which fits your control panel project.

Last updated Aug 17, 2026

Choosing a control panel enclosure is more than picking a metal box. You need enough room for your DIN rail, terminals, and wiring, plus a protection level that matches where the enclosure will live. Here, the Hoffman A302408LP and the Unity Type 1 Electrical Enclosure sit at opposite ends of the size and price spectrum, so the right choice depends on the scale of your project.

Quick Verdict

The Hoffman A302408LP costs $495.00 and the Unity 12126SCNK costs $40.00 - a $455 gap that makes sense only if you need the larger industrial footprint. If you're wiring a compact indoor control panel or junction box, the Unity enclosure is the practical pick. If you're building a substantial industrial control panel with room to grow, the Hoffman is the stronger candidate.

Where Each Wins

Hoffman A302408LP. The Hoffman is the pick when your control panel layout demands a wide, deep interior. The larger footprint leaves room for multiple DIN rail assemblies, bigger terminal blocks, and the kind of component clearance that makes wiring and maintenance easier. It's aimed at industrial applications and comes ready for AC equipment, so it fits a shop-floor or process setting. If you expect your panel to grow, the extra space is a genuine advantage.

Unity 12126SCNK. The Unity is the better fit when space is tight and your components are modest. Its compact footprint tucks into a wall-mounted junction box location without dominating the wall. The square shape and lighter scale make it easy to position in a small electrical room or production line. If you're protecting a simple control circuit, a relay bank, or a compact DIN rail setup, the Unity gives you a clean, dedicated home without requiring a large mounting area. The smaller size also simplifies handling during installation.

Product Notes

Hoffman A302408LP

Hoffman A302408LP 30" x 24" x 8" NEMA Type 12 Industrial Control Panel Enclosure

The Hoffman arrives as a new but open-box unit, and it includes an original box plus a Phoenix Terminal Block 3003347 that was added by the facility before sale. That pre-installed terminal block is a genuine convenience for wiring a control panel, since you don't have to source and mount it separately. The enclosure has never been used, which is a plus for an industrial housing. On the other hand, this is not a factory-sealed purchase, and the added terminal block means the interior is not in its exact factory configuration. If you need a completely untouched enclosure or prefer to select your own terminals, that's a consideration.

Unity 12126SCNK

The Unity 12126SCNK is a UL Listed steel enclosure made in the USA, and it's offered as a new open-box unit that was purchased in bulk and never used, though it may show minor handling marks from storage. The gray powder-coated finish and screw-on non-hinged cover make it a straightforward indoor solution for electrical panels, control systems, and junction boxes. Its clean design and easy wall-mounting are practical for a compact NEMA 1 application. The main limitation is the non-hinged cover: you have to loosen fasteners and remove the cover completely to access the components, which is less convenient than a swing-out door if you need frequent access.

Final Choice by Use Case

If your project is a large industrial control panel that needs robust protection, a wide interior, and the convenience of a pre-installed terminal block, the Hoffman A302408LP is the enclosure to build around. If you need a compact indoor enclosure for a smaller control circuit or junction box, the Unity 12126SCNK is the practical pick. Let the size of your wiring and the environment do the deciding.
