ABB A9-30-10 AC Contactor is a three-pole, AC-operated motor-contactor in ABB’s A9 line, designed to switch three-phase loads. It supports coil voltages of 220–230 V at 50 Hz or 230–240 V at 60 Hz and is rated for control of power circuits up to 690 V AC or 220 V DC. A common variant is the 1SBL141001R8010 coil option for 220–230 V/50 Hz or 230–240 V/60 Hz. The A9-30-10 is typically used to control AC motors and other three-phase loads in industrial automation.
