The ABB 3AUD0000000677 is a packaged ultra-low harmonic HVAC drive with an integrated circuit breaker, rated 25 Hp at 34 A under light-overload use per UL, on a 440-480 V three-phase supply. It comes in a Frame R6 size with a NEMA Type 1 enclosure and IP21 protection — meaning it's built for indoor panel mounting where drips and falling dust are the concern, not washdown or outdoor weather. The drive handles both 50 and 60 Hz line frequencies, so it's at home on either a 50 Hz or 60 Hz grid without derating the output.
