Rule of thumb: if you ever use a hose or chemical cleaners, start at NEMA 4; choose 4X for corrosives or salt fog.
Best for clean, dry interiors. Basic protection from contact and light dust. Good for parkade garage doors.
| Highlights | Typical Use |
|---|---|
|
• Powder‑coated steel cabinet • Hinged front access • Compact, serviceable layout |
• Offices, equipment rooms • Retail back‑rooms • Dry commercial bays |
Includes a GDI‑Controller mounted inside the enclosure. Avoid washdown, spray, or conductive dust — step up to NEMA 12 or 4.
Sealed for hose‑directed water and routine washdown. Good for car wash overhead doors.
| Highlights | Typical Use |
|---|---|
|
• Gasketed door & sealed penetrations • Robust hardware for frequent cleaning • Weather‑exposed mounting OK |
• Loading docks & sanitation areas • Car washes & ag rinse zones • Outdoor perimeters |
Includes a GDI‑Controller mounted inside the enclosure. For corrosive cleaners or salt‑fog, use NEMA 4X (Stainless).
For corrosive or sanitary sites — coastal, chemical, food & beverage washdown, farm garage doors, and mining rolling steel doors.
| Highlights | Typical Use |
|---|---|
|
• Stainless steel (304 or 316) • Superior corrosion resistance • Smooth, cleanable surfaces |
• Food & beverage processing • Coastal docks / marine adjacent • Chemical splash & spray areas |
Includes a GDI‑Controller mounted inside the enclosure. 316 is commonly preferred around chlorides (e.g., salt spray).
For dusty interiors with lint or light oil‑mist. Gasketed, non‑vented design. Good for mining environments & rolling steel doors.
| Highlights | Typical Use |
|---|---|
|
• Door gasket reduces dust ingress • Non‑vented cabinet • Separates controls from shop air |
• Fabrication shops (saw/metal dust) • Warehousing with airborne dust • Light industrial w/ oil‑mist |
Includes a GDI‑Controller mounted inside the enclosure. Not for hose‑down — move to NEMA 4 if regular spray is present.
| Model | Protection Focus | Typical Use | Material | Notes |
|---|---|---|---|---|
| NEMA 1 — Steel | Basic indoor contact protection | Clean, dry interiors | Powder‑coated steel | Not for washdown or heavy dust |
| NEMA 4 — Extreme Wet Zones | Hose‑directed water / spray | Washdown & outdoor eaves | Sealed housing | Good for routine cleaning |
| NEMA 4X — Stainless (304/316) | Wet + corrosive resistance | Food/chemical & coastal | Stainless 304/316 | Best where chemicals or salt are present |
| NEMA 12 — Dust‑Tight | Dust / lint / light oil‑mist | Shops & warehouses | Gasketed steel | Non‑vented; indoor only |

| Question | Answer |
|---|---|
| How do I pick between NEMA 4 and 4X? | Both address spray and washdown. Choose 4X when corrosion resistance is important (salt, chemicals, or F&B). If it’s only water exposure and no corrosives, NEMA 4 is often sufficient. |
| Can I use vented enclosures in dusty areas? | Generally no. For dust‑prone interiors, use non‑vented, gasketed designs like NEMA 12. |
| Cold storage considerations? | Use sealed designs (NEMA 4/4X) and select glands/gaskets rated for low temperatures. |
| What about compliance? | Verify selections with your AHJ and follow applicable standards (e.g., UL‑325 for door operators). |
