What the AF26 frame and N3R enclosure mean for panel fit
The AF2612-2C1J is an AF26-frame contactor with normally-closed (NC) main poles, 3-phase switching, and a NEMA 3R enclosure — meaning it's built for outdoor or washdown-adjacent locations where rain, sleet, or dripping water are present, but not hose-down pressure. The NC contacts stay closed when the coil is de-energized, so this is the contactor you spec for fail-closed loads — like a holding brake or a heater that must stay on if control power drops.
Lifecycle status — still an active line item
For a critical spare on a conveyor or pump panel, this part is a fast mover in the AF26 family; keep one on the shelf if the line runs NC contactors.
