The ABB AF75-30-11-70 is a 3-pole non-reversing contactor rated 80 A, part of the AF75 series. The 100-250 VAC/DC coil gives it a wide control voltage range — useful for installations where control supply varies or where DC is the only available control power. The 80 A rating is the thermal current (Ith) at 40°C; for AC-3 motor duty, derate to the motor full-load current per the manufacturer's table. Built into a standard panel footprint with the 1 NO + 1 NC auxiliary contact block already integrated. The non-reversing design means it switches load in one direction only — pair two for reversing applications, plus mechanical interlock.
Control coil voltage — what it means for fit
The 100-250 VAC/DC coil is a wide-range design, meaning it picks up and holds across that entire voltage without needing a separate coil for 120 V vs. 240 V systems. Common in global panels where both 110 V and 220 V control supplies are present. DC operation is at the same voltage range — confirm polarity (no free-wheel diode needed; the coil is designed for both AC and DC).
