Purpose-built enclosure

The Wiegmann SC121204G is a NEMA 1 rated galvanized steel enclosure designed to house electrical components in indoor environments. It suits installers and maintenance teams who need a wall-mounted box with a solid cover for line protection or circuit breaker applications.

Thermal and power behaviour

The galvanized steel body dissipates heat passively without fans so acoustic output is zero and no power is drawn by the enclosure itself. The 16 gauge construction and 4 inch depth provide a usable opening depth of 3.88 inches for component airflow while maintaining a sealed, screw-on cover.

Included hardware impact

Plated steel captive screws and self-tapping mounting screws are supplied so the cover secures quickly and the unit fastens to the wall without extra trips to the parts bin. Embossed mounting holes speed alignment and the CSA, cULus and UL Listed markings confirm compliance for North American electrical installations.

Questions about this item

How do I mount the SC121204G enclosure to the wall, and what step is often missed?

Use the embossed mounting holes on the back of the 16 ga galvanized steel body; the step often missed is drilling pilot holes for the self-tapping screws included in the package.

What maintenance does the captive-screw cover require over time?

Check the plated steel captive screws periodically for corrosion on the galvanized finish and retighten them to maintain the NEMA 1 seal against dust ingress.

What is the first limitation when running equipment continuously inside this enclosure?

The usable opening depth of 3.88 in limits the size of components you can install, which becomes the constraining factor before heat dissipation in the 12 in by 12 in by 4 in cavity.
