The ABB 3AXD50000760961 is an ACQ580-01 wall-mounted LV AC drive, frame size R2, built for 3-phase 500–600 V input at 50/60 Hz. It carries UL heavy-duty ratings of 2 Hp / 2 A and light-overload ratings of 3 Hp / 3.9 A at 575 V. The NEMA Type 1 enclosure with IP21 protection suits indoor panel mounting where drip and dust ingress are minimal.
The light-overload rating of 3.9 A (3 Hp) applies to variable-torque loads such as centrifugal pumps and fans where peak demand is brief. For water and wastewater applications — the drive's designated use — the light-overload curve is the one that governs pump sizing; the heavy-duty figure provides headroom for intermittent overloads.
