Allen-Bradley 709-AOC U Coil

Allen-Bradley 709-AOC U Coil is a 120 VAC coil designed for use with Allen-Bradley Bulletin 709 motor starters, a NEMA-size 0 starter family used to energize motors in control circuits. The 709-AOC coil variant provides a standard 120-volt AC coil rating (60 Hz in typical installations), enabling reliable actuation of the starter’s contacts to start and stop motor loads in industrial automation environments. In practical setups, these coils are commonly paired with suppression hardware such as the 1401-N10 suppressor catalog number, as documented in Allen-Bradley device bulletins for 709 motor starters, helping to control arcing and protect drive electronics. Distributor listings confirm the 709-AOC designation and its 120 V AC coil specification, with multiple sources noting the same coil voltage for the 709 family. When selecting replacement coils, ensure you match the 709 series family and the 120 VAC rating to maintain proper coil energization, timing, and overall reliability of the motor-start function. This coil variant is typically used in legacy or replacement scenarios for Bulletin 709 starters within industrial control panels and machine control circuits, delivering dependable actuation in automation racks, motor control centers, and OEM equipment.
