The ABB 3AXD50000296781 is a wall-mounted LV AC drive from the ACH580 series, purpose-built for HVAC applications. It delivers 46.2 A continuous output from a 208-240 V three-phase supply, with an apparent power rating of 18 kV·A and light-overload capability to 15 Hp.
The 46.2 A normal-use current (In) is the continuous rating at the drive's full ambient of 40 °C — match this to the motor FLA plus any cable derating. The IP55 enclosure and NEMA Type 12 rating mean it's suitable for washdown or dusty mechanical rooms without an additional cabinet. Frame size R3 keeps the footprint compact for wall-mounting, but verify clearance for the required bending radius of incoming power cables.
