The ABB 3ABD00057879 is a 3-phase LV AC machinery drive in Frame Size R1, rated for 380-480 V input at 47.5-63 Hz. Normal-use output is 1.5 kW at 4.0 A; heavy-duty use drops to 1.1 kW at 3.3 A. Light-overload use matches the normal-use power at 1.5 kW but with a slightly lower current of 3.8 A. The module is IP20, Open Type, and carries IE2 efficiency.
Mounts as a module; Frame Size R1 determines the physical footprint for panel layout and DIN-rail or backplate planning. The IP20 enclosure suits clean, dry cabinet environments — no gland plate sealing required, but keep it away from washdown zones. Input voltage covers 380-480 V three-phase, which covers most European and North American industrial mains without a transformer.
The normal-use rating (1.5 kW, 4.0 A) applies to standard constant-torque loads like conveyors or pumps. The heavy-duty rating (1.1 kW, 3.3 A) is the one to use for variable-torque or high-starting-torque applications — it's the lower current limit that governs when the motor demands more at low speed. If your load profile is mostly light, the light-overload rating (1.5 kW, 3.8 A) gives you the same power but at a slightly reduced current, which can save on cabling or fuse sizing.
