The ABB 3AXD50000706457 is an ACQ580-PC-156A-4 LV AC packaged drive — a complete motor-start assembly with circuit breaker and fuse integrated into a NEMA Type 1 enclosure. It delivers 156 A continuous in light-overload duty (125 Hp at 460 V), sized for pump and fan applications where the drive, protection, and disconnecting means arrive as one line-side-ready unit.
Frame R7 is the mechanical footprint — this determines back-panel drilling, cable entry clearance, and mounting-hole pattern for the enclosure. The 156 A light-overload rating (UL) is the continuous output current at 440–480 V; if your motor full-load amps exceed that, you need the next frame up. Input voltage range is 440–480 V three-phase at 50/60 Hz, so it lands on standard North American 480 V distribution without a transformer.
Enclosure and protection
NEMA Type 1 enclosure (IP21) means indoor use only — no protection against hose-down or dust ingress. The IP21 rating allows some dripping water but not pressurized spray; mount in a clean, dry electrical room or cabinet. The integrated circuit breaker and fuse reduce external wiring and panel space compared to a separate drive + disconnect combination.
