The ABB 3ABD00045121 is an ACS380-series LV AC machinery drive module rated 0.55 kW normal-use output at 1.8 A, with heavy-duty capability at 0.37 kW / 1.2 A. Input is 380-480 V three-phase, 47.5-63 Hz. Frame size R0 keeps the footprint compact; IP20 enclosure suits panel-mount installations where the drive is protected from direct contact.
Duty ratings and real-world fit
Three duty ratings are listed: normal use (0.55 kW / 1.8 A), light-overload (0.55 kW / 1.7 A), and heavy-duty (0.37 kW / 1.2 A). The heavy-duty figure governs continuous operation at higher ambient or with constant torque loads like conveyors; normal-use covers variable-torque fans and pumps. The light-overload current (1.7 A) is close to the normal-use rating, indicating the drive can sustain near-rated output without derating for most applications.
Frame R0 determines the mounting hole pattern and overall dimensions — verify panel cutout against the ACS380 installation manual. IP20 means no gasketing; install in a clean, dry enclosure. NEMA Open Type enclosure rating confirms it is not intended for outdoor or washdown environments. Efficiency class IE2 meets current minimum standards for most regions; no premium IE3/IE4 requirement for this power band.
