The ABB 3AXD50000706518 is an ACQ580-PC-077A-6 packaged drive — a LV AC drive with an integrated circuit breaker and fuse, sized for 3-phase 525-600 V supplies. It carries a UL light-overload rating of 75 Hp and 77 A at 575 V, which is the rating that governs motor sizing in North American installations. Frame size R5, NEMA Type 1 enclosure with IP21 protection.
The integrated circuit breaker and fuse eliminate separate line-side protection components. That saves panel space and wiring time, but it also means the SCCR and coordination are fixed to the drive's internal design — no swapping in a different breaker for a higher fault current.
