The ABB 3AXD50000275489 is a low-voltage AC drive module for HVAC, rated 4 kW normal-use output at 9.4 A on a 400 V three-phase supply. It ships as a control unit included in frame size R1, with IP20 open-type enclosure. Input accepts 380 to 480 V, 47.5 to 63 Hz, three-phase. Normal-use output current is 9.4 A; heavy-duty use drops to 7.2 A at 3.0 kW. Light-overload use is rated 8.9 A at 4.0 kW. UL-listed output currents are slightly lower: 7.6 A normal-use, 4.8 A heavy-duty, 7.6 A light-overload. Built-in BACnet communication is standard, with 2 analog inputs, 2 analog outputs, and 6 digital inputs / 3 digital outputs. Standby loss is 15 W; typical power consumption under load is 140 W. Efficiency meets IE2 level.
Rated for maximum 50 °C ambient. Sound level is 63.1 dB(A). The module contains a lithium coin cell (CR2032, 220 mAh, 3 V) for real-time clock backup.
