100-C09D10 | Allen-Bradley MCS-C Contactor, IEC, 9A, 110V/50Hz, 120V/60Hz

The Allen-Bradley 100-C09D10 is a 3-phase contactor designed for controlling electric motors in industrial applications. It enables reliable switching of power circuits and provides compact motor control up to 5 HP at 460V. This device supports both direct-on-line starting and integration into motor starters or control panels. It ensures safe engagement and disengagement of the motor circuit based on control signals. This contactor is ideal for moderate load applications and conforms to global IEC standards.

The coil of the 100-C09D10 operates at 110V AC when supplied at 50 Hz, and 120V AC when operated at 60 Hz. This dual-frequency design ensures compatibility with a wide range of international electrical systems. The AC coil provides quick and reliable pull-in for contact engagement. It also contributes to reduced control circuit complexity in mixed-frequency environments. Coil terminals are clearly marked and easy to connect using screw clamps.

The 100-C09D10 is a 3-pole contactor, suitable for controlling three-phase motors or circuits. Each pole switches one phase, ensuring synchronized motor start/stop operations. This configuration is standard for three-phase industrial systems. It also includes an auxiliary contact: 1 Normally Open (NO), used for signaling or interlocking. This makes it useful not only for power switching but also for logic control circuits.

Yes, the 100-C09D10 is compliant with IEC/EN 60947-4-1 and 60947-5-1 standards. These standards define requirements for electromechanical contactors and auxiliary devices. Compliance ensures safe operation, consistent performance, and global acceptance in electrical systems. The contactor is suitable for CE-marked equipment and installations across regions. This allows OEMs and engineers to use it confidently in global applications.

Yes, the 100-C09D10 is still actively manufactured by Rockwell Automation under the Allen-Bradley brand. It is a current model within the IEC 100-C contactor family. Replacement parts and accessories are readily available. For large projects or spares, it can be sourced through official Rockwell distributors. If a higher-rated or specialized version is needed, other 100-C series variants can be considered.
