HVAC packaged drive with e-clipse bypass
The ABB 3AUD0000002066 is an HVAC packaged drive integrating an e-clipse bypass and a circuit breaker disconnect in a single NEMA Type 1 enclosure. This is a 3-phase unit rated for 440-480 V input at 50/60 Hz, delivering 250 Hp (302 A) under light-overload UL conditions. The e-clipse bypass lets the motor run directly off line power if the drive faults, keeping the air handler or chiller moving while you swap the VFD module.
Frame R9 and enclosure fit
Frame R9 is the physical footprint for this drive package. The NEMA Type 1 enclosure is indoor-only, drip-proof, with knockouts for conduit entry — no rain or washdown exposure. IP21 protection means fingers and small tools stay out, but it's not sealed against moisture; mount it in a conditioned equipment room or mechanical penthouse, not on a roof pad.
This order code carries an active lifecycle status — ABB still lists it as a current catalog item. No last-time-buy or phase-out notice is known.
