Allen-Bradley 100-C23DJ300 Contactor Relay

Allen-Bradley 100-C23DJ300 Contactor Relay is a four-pole IEC contactor with a 24 V DC coil designed to switch three‑phase loads in industrial control systems. It provides three normally open and one normally closed main contacts (3NO-1NC) across its four poles, enabling straightforward line switching and safe fail‑safe wiring. The main contact rating is specified as 23 A per pole on the 100-C23EJ300 cut sheet, and line-side wiring is accomplished via screw terminals. Some retailer listings describe the DJ300 variant as including an integrated diode across the coil and, in certain listings, a 30 A rating; however, Rockwell documentation for the 100-C23EJ300 confirms 23 A per main contact and a 24 V DC coil. The 100‑C family includes models such as 100-C23J300 and 100-C23EJ300, and this DJ300 variant aligns with the family’s IEC contactor configuration for control circuits in automation applications such as machine control, conveyors, and pumps.
