Drive selection memo — solar pump duty
The ABB 3AXD50001195809 is an ACQ80-01-075KW-4 wall-mounted drive purpose-built for LV AC solar pump applications. Heavy-duty use is rated at 55 kW, 105 A; light-overload use at 75 kW, 138 A. The drive includes the control unit and is enclosed to IP21 with NEMA Type 1 protection, suitable for indoor installation where drips and falling dirt are the main concern.
Frame size R6, wall-mounted. The IP21 / NEMA 1 enclosure means no gland plate sealing is required for conduit entry — standard knockouts suffice. For audit purposes, note that the WEEE category is 4 (Large Equipment, any external dimension >50 cm), so end-of-life disposal routing must be documented under local WEEE schemes.
Communication and interfaces
CAN protocol is onboard. One RS-485 hardware interface is provided. Frequency range is 47.5–63 Hz.
