Drive unit, R6 frame, 15 kW normal duty
This ABB 3AXD50000047503 is a wall-mounted drive unit in frame size R6, delivering 15 kW normal-use output at 27 A from a 380–500 V three-phase supply. The heavy-duty rating drops to 11.0 kW at 21 A, while light-overload use holds at 15.0 kW with 26 A — a split that matters when sizing for constant-torque vs variable-torque loads. The IP21 enclosure suits indoor panel mounting; the Type 1 NEMA equivalent means no additional drip shield needed for most control rooms. Two analog inputs and two analog outputs are onboard, plus six digital inputs and two digital outputs. Communication is CAN-based — no onboard Industrial Ethernet, so a separate fieldbus adapter or gateway is required for PROFINET or EtherNet/IP integration. The standby loss of 52 W and power consumption of 533 W at rated load give the panel cooling engineer something to budget for.
Duty ratings and load profiles
The normal-use current of 27 A defines the continuous rating for most pump and fan applications. The apparent power output of 23 kV·A aligns with the 15 kW real-power rating at the listed power factor of 1.0.
Wall-mounted installation, IP21, rated for ambient temperatures up to +55 °C and humidity from 5 to 95% non-condensing. Altitude rating of 4000 m means no derating at most common plant elevations. Sound level at 71 dB(A) — noticeable in a quiet control room; factor in ear protection if the drive is near operator stations. The WEEE category 4 (Large Equipment >50 cm) applies for end-of-life disposal in EU markets.
