The 3AUD0000000067 is an ABB ACH580-series HVAC drive with an integrated circuit breaker disconnect, rated for 125 Hp light-overload use under UL listing, delivering 156 A output current. It runs on 380-480 V three-phase input at 50/60 Hz. The NEMA Type 3R enclosure means this drive is rated for outdoor installation — rainproof, sleet-resistant, and suitable for rooftop or wall-mount HVAC applications where the drive lives alongside the equipment it controls, not in a conditioned electrical room.
The 156 A UL light-overload rating governs the motor sizing: this drive handles a 125 Hp motor under typical variable-torque HVAC loads (fans, pumps, compressors) without oversizing. The integrated circuit breaker disconnect eliminates a separate branch-circuit protective device — saves a panel space and a wiring step. The 380-480 V input range covers common North American 460 V and 480 V distribution, plus 400 V international supplies.
