The FUJI NEMA1-20E2-247 is a NEMA 1 enclosure kit for FUJI ACE series AC drives. It ships as a field-installable kit containing the NEMA box, mounting screws, and top cover — everything needed to convert an open-chassis ACE drive into a NEMA 1 enclosed unit for indoor use where falling dirt and light splash are the main concerns.
What the NEMA 1 rating means for fit
NEMA 1 is the indoor general-purpose enclosure rating. It protects against incidental contact with live parts and keeps falling dirt out of the drive compartment. It does not seal against water jets, hose-down, or corrosive atmospheres — that's NEMA 4X or 12 territory. For a panel builder or MRO storeroom, this kit is the standard way to mount an ACE drive on a wall or in a dry electrical room without needing a separate enclosure. The kit's overall depth is 6.3 in, so verify the drive's heat sink clearance behind the panel — the NEMA box adds depth beyond the bare drive chassis.
