Allen-Bradley 71A11 Contactor Starter Coil AC

Allen-Bradley 71A11 is an AC coil for NEMA Size 1 contactors used in Allen-Bradley Bulletin 700-Series K starters. It accepts 380 V AC at 50 Hz or 440 V AC at 60 Hz, aligning with common 380/440 V control power and regional frequency standards. The coil energizes the starter's magnetic mechanism to close the contact set and deliver motor power when control voltage is applied. Specifically designed for use with Bulletin 700-Series K, Size 1 starters, this coil supports motor-control circuits where a compact, high-voltage AC coil is required. In typical industrial applications such as conveyors, pumps, and fans, the 71A11 coil provides reliable actuation for small- to mid-size motors when paired with the appropriate size-1 contactor. To ensure compatibility, confirm that your starter catalog number uses the 71A11 coil code and that the voltage specification matches your power system (380 V 50 Hz or 440 V 60 Hz).
