The ABB 3AXD50000865161 is an ACQ580-31-065A-4+N6050+X1681 ULH irrigation wall-mounted single drive, running on 440-480 V three-phase at 50/60 Hz. It delivers 50 Hp (65 A) in light-overload duty and 40 Hp (52 A) under heavy-duty use — the rating that governs continuous motor operation in a pump or fan application.
The R6 frame size houses the power stage and control board in a NEMA Type 1 enclosure rated IP21 — suitable for indoor wall mounting where drips and falling dirt are present but not hose-down. The irrigation ULH variant includes the N6050 and X1681 option codes, which tailor the I/O and firmware for pump-specific functions like flow control and dry-run protection.
