The ABB 3AXD50000956753 is a frame-size R4 LV AC micro drive for HVAC fan and pump duty. It delivers 11 kW normal-use output (48.0 A) on a 200–240 V three-phase supply, with a heavy-duty rating of 7.5 kW (30.8 A) for constant-torque loads. Light-overload use holds at 11 kW (46.2 A). UL ratings match: 15 Hp normal-use (46.2 A), 10 Hp heavy-duty (32.0 A), and 15 Hp light-overload (46.2 A). The drive includes a control unit, runs on BACnet communication, and is rated IP20 with a NEMA Open Type enclosure.
Heavy-duty current (30.8 A) governs constant-torque applications like screw compressors or positive-displacement pumps. The 200–240 V input range covers common North American 208 V and 240 V supplies; frequency acceptance spans 47.5 to 63 Hz, so it handles 50 Hz and 60 Hz grids without reconfiguration. Standby loss sits at 35 W — relevant for continuously powered installations where idle heat adds up.
Integration notes
Mounts as a module — no separate control unit to order. The drive offers 2 analog inputs and 1 analog output for transducer feedback; digital I/O counts 4 inputs and 2 outputs. BACnet is the onboard fieldbus; no industrial Ethernet interface is fitted. Efficiency class IE2, power factor 0.98. Ambient temperature ceiling is 60 °C. Sound pressure level measures 69 dB(A) — typical for a ventilated drive of this power class.
