The ABB 3AXD50000956838 is an ACH180-04S-033A-4 LV AC micro drive module sized for HVAC applications. Normal-use output is 15 kW at 32.0 A on a 400 V three-phase supply (47.5–63 Hz). Heavy-duty use derates to 11 kW at 25.0 A; light-overload use holds 15 kW at 30.5 A. UL ratings at 460 V: 20 Hp / 27.0 A normal-use, 15 Hp / 21.0 A heavy-duty. Frame size R3, IP20, open type.
Ratings & fit
The normal-use current (32 A) is the spec to match against motor FLA for continuous duty. Heavy-duty current (25 A) governs for cyclic or high-start-torque loads. Power factor is 0.98. Standby loss is 23 W — relevant for panel thermal budgeting. Sound level is 66 dB(A). Altitude rating is 2000 m without derating. Analog inputs: 2; analog outputs: 1. Digital I/O: 4 inputs, 2 outputs. Communication is BACnet — no onboard Industrial Ethernet. This is a dedicated HVAC drive; no PROFINET or EtherCAT option in this order code.
