The ABB 3AXD50000707300 is a drive module for solar pump applications. It delivers 7.5 kW normal-use output at 17 A from a 380-480 V 3-phase supply, with a 12 kV·A apparent power rating. The frame R2 package includes the control unit.
Duty ratings — normal, heavy, light overload
Three duty classes are defined: normal use (Pn 7.5 kW, In 17 A), heavy-duty use (PhD 5.5 kW, IhD 12.6 A), and light-overload use (PlD 7.5 kW, IlD 16.2 A). Light-overload matches the normal power but at a slightly lower current, which tells you the drive can sustain 7.5 kW under moderate overload profiles without tripping.
Input and environment
Runs on 380-480 VAC 3-phase, 47.5-63 Hz. Ambient temperature max 50 °C, humidity 5-95% non-condensing. Standby loss is 25 W, so it idles cool; full-load power consumption is 259 W. Sound level 58.8 dB(A) — noticeable in a quiet room but not loud for a drive this size.
Two analog inputs and two analog outputs are onboard, plus 6 digital inputs and 3 digital outputs. Communication is CAN-based — no onboard Ethernet, so if you need Modbus TCP or PROFINET, you'll add an option module or a gateway. The lithium coin cell (CR2032, 220 mAh) backs the real-time clock and parameter storage; it's field-replaceable.
