The ABB 3AXD50000750252 is an ACH531-01-02A7-4 LV AC wall-mounted drive built for HVAC duty. It delivers 0.75 kW normal-use output at 2.6 A, fed from a 380-480 V three-phase supply. Standby loss sits at 14 W — low enough that ventilation planning is straightforward in a standard IP20 enclosure.
The 0.75 kW / 2.6 A rating at normal duty maps to a standard 1 HP induction motor on 400 V. Light-overload use is rated the same 0.75 kW at 2.5 A — no headroom above nameplate, so size up if the load profile includes sustained overloads. Efficiency is IE2 class, which meets current EU minimum standards for this power band.
Open-type NEMA enclosure, IP20 — intended for clean indoor panel mounting. Ambient temperature limit is 40 °C maximum; above that, derate output current per the drive's thermal curve. Frame R1 units are typically wall-mounted with clearance above and below for airflow. No forced cooling required at this power level, but keep the 14 W standby loss in mind for sealed cabinet heat budgets.
