Product details

The ABB 3ABD00049879 is an ACH531-01 wall-mounted HVAC drive rated 5.5 kW normal-use output at 12.6 A, fed from a 380-500 V three-phase supply. IP20 enclosure means it lives inside a cabinet, not out on the wet wall — plan the gland plate and cooling accordingly.

The 12.6 A normal-use current (12 A light-overload) matches a standard 5.5 kW four-pole induction motor on 400 V. IE2 efficiency is the baseline for HVAC fans and pumps — no premium-motor premium required. Frequency range 47.5-63 Hz covers 50/60 Hz grids without derating. Open-type NEMA enclosure confirms this is a panel-mount drive, not a standalone unit.
