UL-listed for light-overload duty at 125 Hp and 125 A, it takes a 500 to 600 V three-phase input at 50/60 Hz. That means it handles the full load of a large rooftop unit or chiller compressor without external bypass contactors — the bypass is built in, so if the drive faults, the motor runs direct across the line through the bypass path, keeping the air moving. The NEMA 3R enclosure lets it mount outdoors or in unconditioned mechanical rooms; no additional weather shelter needed. ## What the UL ratings mean for fit The 125 A light-overload figure (UL) sets the continuous output current the drive can deliver without derating. For a 125 Hp motor at 480 V, that current lines up with a standard NEMA frame size. If your motor nameplate draws more than 125 A at full load, you need the next frame up. The 500-600 V input range covers 480 V and 600 V class supplies; the 50/60 Hz rating means it works on either frequency without reconfiguration — important for retrofit jobs where the plant frequency is fixed. ## Deployment context NEMA 3R means rainproof and sleet-resistant — mount it on a roof curb, an exterior wall, or inside a mechanical penthouse. The e-clipse bypass automatically transfers the motor to line power if the drive trips on a fault, maintaining fan or pump operation while the drive fault is cleared. That's the key feature for critical HVAC loads where downtime equals a comfort complaint or a process upset.","metaTitle":"ABB 3AUD0000004273 HVAC Drive, 125 Hp, 125 A, NEMA 3R","metaDescription":"ABB ACH580-BCR-125A-6+B058 HVAC packaged drive with e-clipse bypass and circuit breaker disconnect.
