Allen-Bradley 100-C09D10 Electrical Contactor

Allen‑Bradley 100-C09D10 is a three‑pole IEC contactor from the Bulletin 100‑C line, engineered to switch three‑phase motors and other AC loads with a 9 A AC‑3 rating. It uses a 120 VAC coil (coil code D10) and includes one built‑in normally open auxiliary contact (1 N.O.), with line‑side screw terminals for robust wiring. The unit is suitable for control circuits operating at 50/60 Hz and is designed to handle up to 600 V switched line voltage, making it versatile for a range of motor control applications. Typical horsepower compatibility at common supply voltages includes roughly 2 HP at 200 V, 2 HP at 230 V, 5 HP at 460 V, and 7.5 HP at 575 V, enabling reliable starter duty for small to mid‑sized motors such as conveyors, fans, and pumps in commercial and light industrial setups. This model is a compact, maintenance‑friendly option within the 100‑C family, intended for use with standard 100‑C series motor control assemblies and installations requiring a dependable, screw‑terminal contactor with a built‑in auxiliary contact for simple interlocking or signaling.
