The AF80N3-30-11-13 is a 3-pole NEMA 3 contactor from ABB, AC/DC operated and fitted with one normally-open plus one normally-closed auxiliary contact. The NEMA 3 designation means the enclosure is rated for outdoor use — rain, sleet, and dust ingress are kept out without requiring a separate cabinet, which simplifies installation on roof-top HVAC units, irrigation pump panels, or outdoor conveyor drives.
Panel and wiring considerations
The contactor's NEMA 3 enclosure is self-contained, so no additional panel or gland plate is needed for outdoor placement. Spring-cage or screw terminals on the power and auxiliary circuits accept 0.2–2.5 mm² solid or ferruled stranded wire; strip length of 8 mm avoids whiskers under the clamp. The AC/DC coil simplifies control wiring — no polarity concern on DC, and the same coil works across both supply types, reducing spare-part variety on site.
