Wiegmann SC121504 carbon-steel enclosure

The Wiegmann SC121504 is a NEMA 1 rated carbon-steel enclosure finished in ANSI 61 gray powder coat. It measures 15 inches high by 12 inches wide by 4 inches deep with a 16 gauge wall thickness. Designed for indoor electrical installations, it provides line protection for components requiring a solid screw-on cover and wall-mounting capability.

Verify mounting and depth before ordering

Confirm the available wall space accommodates the 15 inch height and 12 inch width of this enclosure. The usable opening depth is 3.88 inches, so ensure internal components fit within this dimension. Check that the mounting surface supports the carbon-steel construction and that the screw-on closure method suits your access requirements. The enclosure includes self-tapping screws and embossed mounting holes for installation.

Indoor thermal performance with screw-on cover

The solid cover and 16 gauge steel body provide passive heat dissipation for typical indoor electrical loads. No active cooling is integrated, so thermal performance depends on the installed equipment and ambient conditions. The powder-coated finish resists corrosion in standard indoor environments. Operation is silent with no moving parts or fan noise associated with the enclosure itself.

Questions about this item

Does the SC121504 enclosure include the mounting hardware or do I need to buy screws separately?

The unit ships with self-tapping screws and plated steel captive screws for the cover, so no separate fastener purchase is required for basic installation.

Should I choose the 12×15×4 inch size or a different SC series dimension for my application?

Select this model when you need a 12 in wide, 15 in high, 4 in deep carbon-steel box with a 3.88 in usable depth; other SC sizes change one or more of those dimensions.

What does the NEMA 1 rating mean once the box is mounted on a wall?

NEMA 1 indicates the enclosure is rated for indoor use only, providing protection against contact with live parts and falling dirt but not against water, oil or corrosion.
