The 3AXD50000275755 is an ABB ACH480 series low-voltage AC drive module built for HVAC applications. It delivers 22 kW normal-use output at 50 A on a 380-480 V three-phase supply, with a 47.5-63 Hz input range that covers 50/60 Hz mains.
Normal-use output current is 50 A; heavy-duty use drops to 45 A, and light-overload use sits at 48 A. Under UL listing those figures derate to 42 A normal-use, 40 A heavy-duty, and 42 A light-overload. That UL derating is the number to use for NEC-compliant installations — the IEC figures are for rest-of-world panels. The 22 kW power rating holds across all three duty classes, so the motor sizing doesn't shift, only the thermal headroom on the drive.
Integration and I/O
The drive has 2 analog inputs and 2 analog outputs, plus 6 digital inputs and 3 digital outputs — enough for a basic AHU or pump sequence without an extra I/O module. Communication is BACnet over the built-in port; there is no Industrial Ethernet interface (0 hardware interfaces listed), so if the BMS expects Modbus TCP or BACnet/IP, confirm the protocol variant before wiring. Standby loss is 38 W, which matters for energy-code compliance on systems that idle overnight.
