The ABB 3AUD0000000002 is an HVAC packaged drive combining an ACH580 variable-frequency drive with an e-clipse bypass and a circuit breaker disconnect in a single NEMA Type3R enclosure. It is UL rated for light-overload use at 100 Hp and 124 A output on a 440 to 480 V three-phase supply, 50/60 Hz.
NEMA Type3R means the enclosure is rainproof and sleet-resistant — suitable for outdoor wall-mount or rooftop installation without a separate weather shelter. The integrated bypass and circuit breaker disconnect simplify field wiring: line power lands on the breaker, the bypass lets the fan or pump run at line frequency if the drive is out of service, and the drive section provides variable-speed control for energy savings on HVAC loads.
This part carries an Active lifecycle status from the manufacturer.
