HVAC packaged drive with e-clipse bypass and disconnect
The ABB 3AUD0000000035 is an HVAC packaged drive with e-clipse bypass and disconnect, UL-rated for 125 Hp light-overload use at 156 A output current. Same part, different passport — this is the genuine ABB unit, active in production per the manufacturer. Input is 440-480 V three-phase at 50/60 Hz, housed in a NEMA Type3R enclosure — rainproof and sleet-resistant, suitable for outdoor rooftop or pad-mounted HVAC installations without an additional weather hood.
The 156 A continuous output at 125 Hp (light-overload duty per UL) tells you this drive handles a 125 Hp motor on a typical fan or pump curve without derating. Light-overload means 110% current for 60 seconds — enough for centrifugal load starts, not for high-torque conveyors. The NEMA Type3R enclosure means it lives outdoors; no need for a separate cabinet if local code allows. The e-clipse bypass and disconnect integrated into the package means the motor can run across the line if the drive faults — a common requirement for critical HVAC loads like chiller compressors or hospital AHUs where a stopped fan is a bigger problem than a slightly less efficient run.
