At 480 V, the AC-3 rating is 21 A — that's the motor-switching current it handles for standard squirrel-cage motors, so a typical 10 hp motor at 480 V is well within range. The magnet coil uses spring-type terminals, not screw clamps — that means faster wiring in the panel and no risk of screw loosening under vibration. There is no built-in auxiliary switch block on this variant, so if you need feedback contacts for a PLC or status lamp, you'll add a separate auxiliary contactor block.
