The ABB AF75-30-11RT-69 is a 105 A, three-pole contactor with a wide-range coil accepting 48 to 130 V AC or DC. The coil voltage range means it works across multiple control voltages without swapping coils — handy for panels that run mixed 48 VDC and 110 VAC control circuits.
What the 105 A rating means for fit
The 105 A rating is the contactor's thermal current (Ith) for AC-1 duty, meaning it can carry that current continuously through the main poles in resistive loads. For motor starting (AC-3 duty), the rated operational current is typically lower — around 75 A for this frame size — so size it against the motor's full-load amps, not the Ith number. The built-in 1 NO + 1 NC auxiliary contact block handles feedback and interlocking without an add-on module.
