The 3AXD50000814473 is an ABB ACS180-series low-voltage AC machinery drive module, frame size R4, delivering 18.5 kW normal-use output at 38.0 A from a 380-480 V three-phase supply. That normal-use rating is what you spec for a constant-torque load like a conveyor or pump running at full rated speed. For heavy-duty applications — say a crusher or a centrifuge that needs extra torque at low speed — it's rated 15 kW and 32.0 A, a derating of about 19% on current that buys you headroom on the output stage. It's a module-type drive, meaning it's meant to be panel-mounted — IP20 open type, so it needs a clean, dry enclosure. The 40 °C maximum ambient is standard for drives in a ventilated panel; on a hot floor next to a furnace you'll have to derate or add forced air. Altitude limit is 2000 m, which covers most sites, but above that you lose about 1% per 100 m on current.
The key spec to watch is the heavy-duty current: 32.0 A. That's the number that governs the motor thermal protection setting if you're running a variable-torque load like a fan or a pump with a quadratic curve. The light-overload rating (36.0 A, 18.5 kW) sits between normal and heavy and is the IEC version of the UL light-overload rating — 25 Hp, 34.0 A at 460 V. So if your BOM calls out 25 Hp at 460 V, this drive covers it with the light-overload curve. Power factor is 0.98, which is typical for a modern IGBT drive with a diode front end — no power-factor correction caps needed upstream. Standby loss is 37 W, so if the drive sits idle on a conveyor that only runs part of the shift, that's the heat it dumps into the panel continuously.
RoHS compliant per EU Directive 2011/65/EU and Amendment 2015/863, with a declaration date of 2025-01-06. REACH compliance is declared with substances above the 0.1% threshold (date 2025-09-05). The SCIP number is a7e9add0-620e-4316-8bd6-c358d91bc66b (Finland). UL listing covers the heavy-duty output at 20 Hp, 27.0 A, and light-overload at 25 Hp, 34.0 A, both at 460 V. The WEEE category is 5 (small equipment).
I/O and integration
Two analog inputs, one analog output, four digital inputs, and two digital outputs — enough for basic speed reference and run/stop control, plus a fault relay. Communication is MODBUS over RS-485 (no onboard Ethernet; the hardware interfaces count shows zero industrial Ethernet ports). If your line uses PROFINET or EtherNet/IP, you'll need an option module or a gateway. Sound level is 69 dB(A) — noticeable in a quiet panel room but typical for a frame R4 drive with its cooling fan. The standby loss of 37 W means the fan runs even when the motor is stopped, so factor that into your panel ventilation calc.
