Allen-Bradley 100-C09D10 Motor Contactor Relay

Allen-Bradley 100-C09D10 is a compact, IEC‑style motor contactor from the Bulletin 100‑C family, designed to switch a 3‑phase motor with a 110–120 VAC coil. It is a 3‑pole device with screw‑terminal line‑side connections and a single normally open auxiliary contact (1 NO) for control signaling or interlocking. Rated for AC‑3 duty at 9 A and suitable for motors up to about 4 kW in a typical 60 Hz installation, this model energizes from a 110/120 VAC supply and is intended for standard industrial motor‑control circuits. As part of the 100‑C line, the 100‑C09D10 shares compatibility with common 100‑C accessories and mounting footprints, enabling straightforward replacement or integration into existing control panels and 100‑C based control schemes. The combination of compact form factor, reliable AC magnetic actuation, and a single auxiliary contact makes it a practical choice for on/off motor control in automated equipment and machinery where space is at a premium and wiring must be clean and simple.
