AF1650-30

The ABB AF1650-30 is a high-capacity, three-pole power contactor designed for switching large motors and heavy industrial loads. As part of ABB’s AF series, it features an electronically controlled wide-range coil that operates reliably across a broad AC/DC control-voltage range. The advanced AF coil technology improves tolerance to voltage fluctuations, reduces coil power consumption, and eliminates the need for separate surge suppressors.
