The ABB 3AUD0000000718 is an HVAC enclosed ultra-low harmonic drive with an integrated circuit breaker, rated for 30 Hp / 44 A light-overload use per UL at 460 V, 3-phase, 50/60 Hz. Frame size R6, NEMA Type 1 enclosure, IP21 protection — designed for indoor HVAC installations where harmonic mitigation is needed without external filters.
The 30 Hp / 44 A light-overload rating (UL) means this drive handles a 30 Hp motor continuously at 460 V without derating — the integrated circuit breaker also provides branch-circuit protection, saving panel space and wiring. Frame R6 is the physical size class; verify mounting dimensions against your enclosure cutout. NEMA Type 1 (IP21) suits clean indoor environments — not for washdown or outdoor duty.
Deployment Context
This is a packaged drive for HVAC applications — fans, pumps, compressors — where low harmonic distortion is required to meet IEEE 519 without external line reactors or active filters. The enclosed design with circuit breaker simplifies installation: mount on a wall or panel, land the incoming 3-phase 440-480 V supply, and connect the motor. IP21 means it's fine in a mechanical room or electrical closet but not on a washdown floor.
