The ABB 3AXD50000705979 is an ACQ580-PC-09A0-6+B058 LV AC packaged drive — a complete motor-start assembly with integrated circuit breaker and fuse, sized for 7.5 Hp light-overload duty per UL at 9 A output on a 575 V supply. It takes a 525 to 600 V three-phase input at 50/60 Hz and lives in a NEMA Type 3R enclosure, so it's rated for outdoor or washdown-area installs without a separate panel.
The 9 A light-overload rating (UL) is the continuous output current for a 7.5 Hp motor under typical variable-torque loads — pumps, fans, compressors. The 525–600 V input range covers 480 V and 575 V nominal systems with tolerance. NEMA 3R means the enclosure sheds rain and ice; it's not submersible but works for rooftop or exterior wall-mount without a rain hood.
