The ABB 3AXD50000268856 is a wall-mounted LV AC drive for water and wastewater duty. It runs on 208-240 V three-phase, frame size R7, and carries a NEMA 12 / IP55 enclosure. UL light-overload rating lands at 75 Hp / 211 A; heavy-duty use is 60 Hp / 60 A. That 211 A figure on light-overload tells you the drive can handle a sustained pump or fan curve without derating — typical for variable-torque loads in water treatment. Standby loss is 22 W, which matters for panel thermal planning — not a lot of heat when the motor is stopped, but enough to keep the enclosure venting honest. Efficiency is IE2, and the drive accepts 50/60 Hz line frequency.
The 211 A light-overload rating is the one that drives sizing for most water/wastewater applications — pumps and fans rarely need the full heavy-duty headroom. If your motor plate calls for 60 A or less, you've got margin either way. Apparent power output is 84 kV·A. Input voltage is 208-240 V, so this is a low-voltage drive. Frame R7 means a larger wall-mount unit; plan panel real estate accordingly.
Wall-mounting, NEMA 12 / IP55. That's the key spec for placement: it's rated for indoor use where dust, falling dirt, and dripping non-corrosive liquids are present. No need for a separate cabinet in a typical treatment plant environment. Maximum ambient temperature is 40 °C — keep the cooling air path clear.
