Allen-Bradley Replacement 100-C37D10 Three-Pole Contactor

Allen-Bradley 100-C37D10 is a three-pole IEC contactor designed for starting and stopping three‑phase motors and other inductive loads. Rated for 37 A, it provides line-side screw-terminal termination and is mountable in either a base or DIN-rail configuration to fit common control panels. The coil options include 110 V AC (50/60 Hz) or 120 V AC (60 Hz), allowing compatibility with standard control circuits in North American and international systems. This model includes one normally open auxiliary contact for feedback or interlock signaling. As part of the 100-C IEC contactor family, HP ratings vary with supply voltage—approximately 10 HP at 230 V, 25 HP at 460 V, and up to about 30 HP at 575 V—making it suitable for a range of motor-control applications, from conveyors to pumps and fans, where reliable 3‑phase switching is required.
