The ABB 3ABD00049873 is an active-production ACH531-01 wall-mounted LV AC drive for HVAC applications, rated 0.75 kW normal-use output at 2.6 A, 380–500 V three-phase input. Frame size R0, IP20 open-type enclosure. Efficiency class IE2. Frequency range 47.5–63 Hz covers 50/60 Hz mains.
Normal-use output current is 2.6 A; light-overload use (typically fan/pump duty) is 2.5 A — the difference is small, so the drive is sized for continuous motor load near its nameplate. Input voltage range 380–500 V three-phase suits standard European and North American low-voltage networks. IP20 means it requires enclosure for dust and moisture protection.
