OD1232-SPOT/DIN (1053-1142-ND) is a kit from Orion Fans that allows the user to attach the included fan to a DIN rail, but the clip itself has been a source of confusion for customers dealing with units that need replacement parts, it doesn’t seem to have its own part number and is a somewhat unique part.
This isn’t a perfect solution, but if you’re stuck on this, I believe the adapter clip that they used in this kit is 277-2296-ND from Phoenix Contact. The reason it’s not perfect s because the frame that the clip is attached to in the kit is not included, and I didn’t see any reasonable replacement for that piece when I dug through our available accessories for fans.
Still, I think it’s worth sharing since this clip gave at least one user a headache trying to replace it, having that identified will at least get you a start on addressing the issue if yours has been damaged in the field.
