The LA400FSS is an enclosure with a NEMA 1 rating and a stainless steel front, designed for indoor use where corrosion resistance and a cleanable surface are needed on the operator interface.
What the NEMA 1 / Stainless Steel Front Means for Fit
A NEMA 1 enclosure is intended for indoor use only, providing basic protection against dust and incidental contact. The stainless steel front adds corrosion resistance and allows for washdown cleaning on the operator face, which is common in food, beverage, or pharmaceutical lines where hygiene matters. The stainless steel front also resists rust and staining better than painted carbon steel, making it suitable for environments with occasional moisture or chemical splashes, though the NEMA 1 rating means the enclosure itself is not sealed against hose-down or submersion.
