The ABB 3AXD50000296804 is the order code for an ACH580-01-075A-2+B056, a low-voltage AC wall-mounted drive built for HVAC fan and pump control. It delivers 74.8 A continuous output on a 208-240 V three-phase supply, rated for 25 Hp in light-overload use. The R4 frame carries an IP55 enclosure — suitable for washdown or dusty environments without a separate cabinet.
The 74.8 A normal-use output current (In) is the number that decides cable sizing and upstream protection — not the horsepower figure. On a 208 V supply that current supports roughly 25 Hp; on 240 V the same current yields higher torque margin. Standby loss of 17 W is low for this frame class, meaning the drive's internal cooling fan and control electronics draw under 20 W when the motor is stopped. The IE2 efficiency level is the drive's own internal losses, not the motor's — expect around 97-98% efficiency at full load.
This part carries an active lifecycle status — ABB still manufactures the ACH580-01 series, and the 3AXD50000296804 order code is current. No last-time-buy or successor notice applies.
Wall-mounting is the intended method — the R4 frame has integral mounting points and a gland plate for cable entry. The IP55 rating means it can be hosed down from any direction, so it lives directly on the wall in a plant floor or rooftop HVAC unit without an extra enclosure. Maximum ambient temperature is 40 °C; above that, derate the output current per the drive's thermal curve. The NEMA Type12 equivalent covers indoor use against dust and dripping liquids.
