Product Description
The Allen-Bradley 100-D210EJ11 Bulletin 100-D contactor features a low-voltage electronic coil, direct PLC interface, integrated surge suppression, and Class B insulation. Rated for 24VAC coil voltage (50Hz) and 115-600VAC main circuit voltage, it boasts a 125kW (AC-3) switching power and 210A maximum breaking current. It includes two side-mounted auxiliary contacts (1NO/1NC, snap-in) expandable by two more (2NO or 2NC), three normally open main power contacts (L1, L2, L3) with bolt-in flat-end terminals (ring/terminal lugs optional), and an IP20-rated housing. Compliant with IEC, CCC, CSA, CE, UL, c-UL-us, and RoHS standards, it's suitable for both industrial and non-industrial applications.
Is Your Device Showing These Signs?
The Allen Bradley 100-D210EJ11 commonly experiences issues such as coil failures due to overvoltage or thermal overload, resulting in contactor malfunction. Terminal block damage from improper torque during wiring is a frequent problem. Auxiliary contact block failures lead to control circuit interruption. Inspect the armature assembly for mechanical binding, preventing proper contact closure. Resolve nuisance tripping caused by incorrect overload relay settings or a faulty overload block. Replace worn or pitted main contacts to ensure optimal current carrying capacity and prevent arcing.

Our Repair Process for the
100-D210EJ11
Our repair process for the Allen Bradley 100-D210EJ11 begins with a comprehensive inspection, specifically checking for coil failures stemming from overvoltage or thermal overload, contactor malfunction, and terminal block damage caused by improper torque. We then examine auxiliary contact blocks for failures that interrupt the control circuit. The armature assembly is scrutinized for mechanical binding, which prevents proper contact closure. Nuisance tripping is addressed by verifying and correcting overload relay settings or replacing a faulty overload block. Finally, we replace worn or pitted main contacts to guarantee optimal current carrying capacity and prevent arcing.
