The ABB 3ABD0000058121 is an ACS355-series LV AC machinery drive module, frame size R1, rated for 0.55 kW normal-use output at 1.9 A on a 380-480 V three-phase supply. Heavy-duty use rating is identical at 0.55 kW / 1.9 A, so this unit is sized for a constant-torque load profile — no headroom for intermittent overload beyond the nameplate. Input frequency range covers 47.5 to 63 Hz, which handles both 50 Hz and 60 Hz mains without derating. The IP20 open-type enclosure suits cabinet mounting; the wall-mounting option keeps installation straightforward in a standard panel.
Signal and noise considerations
Wall-mounted in an IP20 enclosure, the drive sits inside a clean panel — no direct exposure to washdown or dust. The 380-480 V input and 1.9 A output are modest, so radiated EMI from the output cables is manageable, but keep the motor cable shielded and bonded at both ends to avoid coupling into nearby sensors. The 47.5-63 Hz input range means the DC bus ripple frequency shifts with line frequency; if you're running a sensitive analog signal near the drive, maintain at least 200 mm separation or use a grounded steel barrier. No built-in EMC filter is specified here, so plan for an external filter if the installation must meet Class A or B limits.
