The ABB AFN012-2E1 is an AFN0 series non-reversing three-phase contactor in a normally-closed (NC) main pole configuration, housed in a NEMA 3R/4 enclosure.
What the Enclosure Rating Means
The NEMA 3R/4 enclosure means this contactor is suitable for outdoor use (rainproof, sleet-resistant) as well as washdown environments indoors — typical for pump panels, irrigation controls, and food-processing equipment where hose-down cleaning is routine.
