The FUJI NEMA1-40E2-24 is a NEMA 1 enclosure kit for the ACE series of AC drives. It includes the NEMA box, screws, and top cover — everything you need to convert an open-chassis drive into a NEMA 1 rated unit for indoor, drip-free environments.
Why the NEMA 1 rating matters
NEMA 1 provides basic indoor protection against falling dirt and incidental contact — no gaskets, no washdown capability. It's the standard choice for clean, dry panel environments where the drive needs a protective cover but doesn't face moisture or dust ingress. The overall depth of 6.3 in tells you the enclosure depth you're working with; check your cabinet clearance before mounting.
