The ABB 3AUD0000003153 is an HVAC-dedicated enclosed ultra-low harmonic drive with a circuit breaker, rated for 400 Hp light-overload output at 477 A per UL conditions on a 460 V supply. Input voltage range is 440 to 480 V, 3-phase, 50/60 Hz, so it lands on standard North American 460 V distribution without a transformer.
NEMA Type 1 enclosure with IP21 ingress protection — suitable for indoor installation where drips and falling dirt are the concern, not washdown or outdoor exposure. Frame size R11 determines the mounting footprint and conduit entry locations; verify panel cutout dimensions against the installation manual before laying out the gland plate.
Product status is Active per the manufacturer's lifecycle record — this is a current-production catalog item, not a phase-out or NRND line.
