What the line item actually is
The ABB ACS355-03E-17A6-2 is a micro drive from the ACS355 family in an R2 frame, built as a module for cabinet building and rated for a 200 … 240 V three-phase input at 50/60 Hz. Apparent power output is 7.0 kV·A, which is the figure an integrator uses to size the motor and the supply breaker for a BOM line — the drive sits at the small end of the ACS355 range, aimed at fractional-to-low-kW induction and permanent-magnet loads.
Control I/O on the lid
Control wiring lands on 2 analog inputs, 1 analog output, 5 digital inputs and 1 digital output — enough headroom for a typical sensor-plus-speed-pot cell, but tight if the line needs separate run-permit and fault-reset channels alongside a reference. Wiring is via the module's spring-cage style terminals; the drive mounts inside the cabinet on its R2 footprint, with a 166 mm × 344 mm × 217 mm envelope that leaves a 2.4 kg net weight to support on the backplate.
Cabinet envelope and thermal limits
Enclosure rating is IP20 Open Type, intended for installation inside a cabinet rather than wall-mounted in a wet area, and the drive is rated to a maximum ambient of 40 °C — derating kicks in above that, and the panel builder has to leave clearance around the R2 heat sink accordingly. Standby loss is 8 W and the drive meets IE2 efficiency class, which is the number that goes into tender scoring and into the panel's standby thermal budget, not the number that drives motor sizing.
Application fit
At 7.0 kV·A apparent output on a 200 … 240 V three-phase feed with 5 digital inputs and 1 digital output, this is the right box for low-horsepower constant- and variable-torque loads such as conveyors, small fans, pumps, and mixers. For long motor cable runs, watch reflected-wave overvoltage at the motor terminals — the cure is a dV/dt or sine filter at the drive output, sized to the cable length and the drive's switching frequency, not at the motor box.
