It's UL-rated for light-overload use at 150 Hp and 144 A, fed by a 3-phase, 500-600 V input at 50/60 Hz. That NEMA 3R rating means it's built for outdoor or unconditioned indoor mounting — rain-tight and sleet-resistant, but not submersible. For a panel builder, the bypass means the fan or pump keeps running even if the drive faults out; the circuit breaker disconnect gives you a local lockable means of isolation without adding a separate disconnect switch. The 144 A light-overload current (UL) is the number that governs conductor sizing and upstream protection for the drive input. Light-overload means it's sized for variable-torque HVAC loads — fans, centrifugal pumps — where the motor rarely pulls more than nameplate current. The 500-600 V input range covers 480 V and 575 V nominal systems common in North American industrial plants; the 50/60 Hz frequency rating means it's not picky about line frequency, so the same unit works on 50 Hz or 60 Hz grids. The 3-phase input is standard for drives this size; single-phase isn't supported.","metaTitle":"ABB 3AUD0000004274 HVAC Packaged Drive, 150 Hp UL, 144 A, 50","metaDescription":"ABB 3AUD0000004274 HVAC packaged drive with e-clipse bypass and circuit breaker disconnect.
