Allen-Bradley 100-C12400 Three Phase AC Contactor is a compact 3-pole motor starter from the 100-C IEC family, designed to switch three‑phase loads in industrial automation. It is rated for up to 25 A and up to 600 V, with a control coil available at 110 V or 120 V AC to suit common control circuits. This device is intended for controlling three‑phase motors and other three‑phase loads, and aligns with Rockwell’s guidance that three‑phase ratings apply to contactors with at least three normally‑open power poles.
