The ABB ACH580 3AUD0000003140 is a 3-phase packaged ultra-low harmonic drive with an integrated circuit breaker, rated for 250 Hp light-overload use at 460 V per UL, delivering 302 A output current. The frame size is R11, and the enclosure is NEMA Type 1 with IP21 protection — suitable for indoor HVAC mechanical rooms, not washdown environments. Input voltage range is 440 to 480 V at 50/60 Hz.
The 302 A light-overload output at 460 V means this drive handles a 250 Hp motor under typical HVAC fan and pump duty profiles — the integrated circuit breaker and ultra-low harmonic design reduce upstream filtering requirements. The R11 frame determines panel cutout and mounting footprint; verify against your existing enclosure layout. NEMA Type 1 / IP21 means it is designed for indoor, non-condensing environments — not for outdoor or washdown service without additional enclosure protection.
