The ABB 3AXD50000275724 is an ACH480-04-033A-4 LV AC drive module built for HVAC duty. It delivers 15 kW normal-use output at 32 A from a 380-480 V three-phase supply, with heavy-duty ratings of 11.0 kW and 25.0 A for tougher loads. Frame size R4, IP20 enclosure, open type.
The drive carries three duty-class output current figures: 32 A normal use (Pn 15 kW), 30.5 A light-overload (PlD 15.0 kW), and 25.0 A heavy-duty (PhD 11.0 kW). For UL-listed installations the normal-use current is 27 A, with heavy-duty at 21.0 A and light-overload at 27.0 A.
Communications and I/O for the controls integrator
BACnet is the onboard protocol — no fieldbus module required for BAS integration. The drive includes 2 analog inputs and 2 analog outputs, plus 6 digital inputs and 3 digital outputs. That's enough for a basic AHU or chiller sequence without an extra I/O slice. A CR2032 lithium coin cell backs the real-time clock; the battery is included, one per unit.
Environmental and mounting notes
Rated for a maximum ambient temperature of 50 °C, IP20 finger-safe enclosure, open type. Standby loss is 37 W; full-load power consumption is 396 W. Apparent power output is 22 kV·A.
