The -01 code marks the IEC installation build. Output rating of three-phase 157 A at 75 kW puts this frame in the heavy-industrial bracket — fans, pumps, conveyors and constant-torque process machinery where the drive carries the full motor nameplate current, not a lightly loaded HVAC fan profile. Enclosure rating is UL Type/NEMA 1, so the unit is intended for a clean indoor cabinet behind a filtered enclosure rather than a washdown or dusty plant floor — match the surrounding panel to the same ingress class. ## Rating that decides the fit The 157 A output figure is the load-bearing number on this listing; motor nameplate full-load current at 75 kW sits below that ceiling with normal service factor, so the drive has the thermal headroom to absorb modest overload peaks without an immediate upsize — but verify the worst-case motor FLA and any cyclic overload duty against the drive's own thermal curve rather than the headline kW. ## Handling and panel footprint Cabinet weight is 35.38 kgs, which puts the unit into two-person lift or hoist territory during installation and replacement — plan the enclosure floor or lower-mounting bracket around that mass rather than a high wall-mount position, and confirm the panel structural rating before slide-in service.","metaTitle":"ABB ACS550-01-157A-4 Drive, 157 A, 75 kW, 380-480 V","metaDescription":"ABB ACS550-01-157A-4 ACS550 drive, 157 A three-phase output at 380-480 VAC rated 75 kW, IEC build, UL Type/NEMA 1.
