Just curious - If your replacing it, why do you need the old Data Sheets?
No one in there right mind should risk using/re-using anything by FP. Contact EATON (Cutler Hammer) Engineering/Replacement services, as they are manufacturing replacement equipment whereby you might be able to re-use the exterior sheet metal, and they will provide new UL listed EATON guts, doors, and hardware. This is becoming big business.
