The ABB 3AUD0000004290 is an ACH580-PDR-052A-6+B058 HVAC drive with an integrated disconnect switch, UL-listed for light-overload duty at 50 Hp and 52 A output. It accepts 500-600 V three-phase input at 50/60 Hz and is housed in a NEMA Type3R enclosure — rainproof and sleet-resistant, suitable for outdoor or unconditioned indoor mounting on a wall or pedestal.
The 52 A light-overload rating (UL) is the continuous current the drive can deliver to the motor without exceeding its thermal limit under typical HVAC load profiles — fans, pumps, compressors with variable torque. The 50 Hp output at 500-600 V matches a standard NEMA-frame induction motor; if your motor nameplate is 50 Hp at 460 V, you need a different drive variant because the current draw at lower voltage exceeds this unit's 52 A limit. The Type3R enclosure means it can be mounted outdoors under a roof overhang or on an exterior wall, but not in direct washdown or corrosive atmospheres — that would require Type4X.
Integration notes
The integrated disconnect switch simplifies panel wiring — it serves as both the drive input disconnecting means and the branch-circuit isolation, eliminating a separate disconnect enclosure. Mount the Type3R enclosure on a flat vertical surface with clearance for the conduit entries at the bottom. The drive ships with the standard ACH580 control panel; for remote monitoring, the embedded Ethernet port supports BACnet MS/TP, Modbus RTU, and embedded web server — no option card needed for basic HVAC plant integration.
