The ABB ACS800/DTC is a converter supply unit built around an M3GP 280SMA 4 motor, rated 20-50 kW at 163-400 V delta, pulling 96-100 A full load. It's an IE2 efficiency machine with IP55 enclosure and EX II 3G equipment protection for explosive dust atmospheres — gas group IIC, so it's certified for hydrogen or acetylene environments if the installation meets the zone constraints. The duty cycle is S9-S9, meaning non-periodic load and speed variations with significant overloads — typical for a converter-fed motor in a process that cycles hard, like a crusher or a centrifuge. The switching frequency sits at 2000 Hz, which keeps audible noise low but isn't high enough to shrink the output filter significantly.
Key Ratings — What They Mean for Fit
The 20-50 kW power range and 96-100 A current rating at 163-400 V delta tell you this is a medium-to-large motor for a converter supply — sized for a 4-pole machine running 600-1500 rpm with 319 Nm torque constant across the speed range. The 94.5% full-load efficiency (IE2) is adequate for a machine designed before IE3 became mandatory in most regions; if your site requires IE3 or IE4 for energy rebates, this won't qualify. IP55 means dust-protected and protected against water jets — fine for indoor industrial environments with washdown, but not submersible. The EX II 3G marking covers Zone 2 gas atmospheres (explosive atmosphere unlikely to occur in normal operation), so it's suitable for paint booths or chemical processing areas with occasional vapor release, but not Zone 0 or 1 continuous hazard zones.
