The ABB AFN21B2-CC8 is a non-reversing, 3-phase contactor from the AFN2 series, housed in a NEMA 3R enclosure — rainproof and sleet-resistant, suitable for outdoor or washdown-adjacent panel locations where drips and falling dirt are a concern.
For BOM-freeze or long-term project planning, this part carries no PCN or LTB flags. It can be specified into new designs with confidence in multi-year availability.
The description identifies this as an AFN2, non-reversing (NR), 3-phase contactor with a circuit breaker (CB) and NEMA 3R enclosure. The NEMA 3R rating means the enclosure protects against rain, sleet, and external ice formation — a common spec for rooftop HVAC units, irrigation pump panels, and outdoor machine disconnects.
