The 3ABD00048283-D: IP21 protection and NEMA Type 1 enclosure suit clean indoor environments — control cabinets, machine rooms, or standalone wall mounting. Wall-mounted format means no floor footprint; the R1 frame is compact enough for panel or wall placement without a pedestal.
Three duty ratings let you match the drive to the load profile without overspending on frame size. Normal use at 4 kW / 9.4 A fits constant-torque loads like conveyors running at full speed. Heavy-duty at 3 kW / 7.2 A gives headroom for high-start-torque applications or sustained overloads — a 3 kW motor on a crusher or extruder. Light-overload at 4 kW / 8.9 A is the sweet spot for centrifugal pumps and fans where the motor rarely pulls full current continuously. The delta between normal and light-overload current (9.4 A vs 8.9 A) is small — the real choice is between the 3 kW heavy-duty floor and the 4 kW normal/light ceiling.
Field considerations
Wall-mounted unit — plan for four fixing points and clearance around the R1 frame for airflow and cable entry. IP21 means no hose-down washdown; keep it inside a panel or at least under a roof. NEMA Type 1 gives basic drip-proofing but not dust or moisture sealing. Input voltage range covers 380-500 V three-phase; confirm your line voltage is within that band before committing the BOM line.
