The ABB AX80-30-11 contactor is a 3-pole AC operated block type contactor designed for industrial use in controlling three-phase motors and power circuits up to 690 V AC. These contactors feature a compact, rugged construction with three main contacts and an internal auxiliary contact block (1NO + 1NC) for control or signaling purposes. The coil voltage varies by specific version (e.g., 220-230 V AC, 110 V AC, etc.). Optional add-on auxiliary contact blocks and accessories can be fitted for expanded functionality.
