This 3AXD50000417834 is an ABB ACH580-01-018A-2+B056, a wall-mounted LV AC drive built for HVAC duty. It's rated 4 kW normal use at 16.9 A on a 200-240 V three-phase supply, with a heavy-duty output of 3.0 kW at 10.6 A. The IP55 / NEMA 12 enclosure handles washdown environments — lift stations, mechanical rooms, anywhere you need to hose the cabinet down without pulling the drive. BACnet is onboard, so it talks directly to the building automation system without an extra gateway.
Ratings that matter for the install
The normal-use current of 16.9 A is the number to size your motor and cable for continuous fan or pump duty. If the load cycles hard — think a chiller compressor or a dirty filter that spikes torque — the heavy-duty curve at 10.6 A gives you the thermal headroom. Light-overload use is listed at 16.7 A, nearly identical to normal use, so for most HVAC fan/pump curves you run at the 16.9 A mark. Standby loss is 13 W, which keeps the energy bill low when the drive is idle but powered.
Wall-mounted in frame size R1. The IP55 / NEMA 12 rating means it's rated for hose-down and dust — fine for a wastewater wet-well cabinet or a rooftop AHU enclosure. Ambient temperature max is 40 °C, so keep it out of direct sun or boiler rooms. The control unit is included, so you don't need to order a separate keypad or logic module.
