Drive identity and headline ratings
The ABB 3AXD50000038987 is an ACH580-01-12A7-4 LV AC wall-mounted drive for HVAC applications, rated 5.5 kW normal-use output at 12.6 A (IEC) and 7.5 Hp light-overload (UL) at 11.0 A. Input voltage is 380-480 V three-phase, 47.5-63 Hz.
Normal-use output (Pn) is 5.5 kW at 12.6 A — that's the continuous rating for typical fan and pump loads. Light-overload (PlD) matches normal use at 5.5 kW but current is capped at 12.0 A, so the drive can handle short-duration overloads without tripping. The UL column shows 7.6 A heavy-duty and 11.0 A light-overload — important for North American installations where UL 508C listing governs the branch-circuit protection.
Enclosure, protection, and mounting
IP21 degree of protection with NEMA Type 1 enclosure — suitable for indoor, clean environments where dripping water and small tools are the main concern. Ambient temperature limited to 40 °C maximum; operating humidity up to 95% RH (non-condensing). Altitude rating of 1000 m without derating.
Built-in BACnet communication protocol — no option card needed for building automation integration. Two analog inputs, two analog outputs, six digital inputs, three digital outputs. No industrial Ethernet interface on this variant, so BACnet MS/TP (RS-485) is the primary fieldbus. Standby loss is 14 W; power consumption at rated load is 213 W.
