Product Description
The Allen-Bradley 104-M12NKD31 is a compact, 12-Amp, 3-phase IEC reversing contactor with a 24V AC coil, suitable for various loads. This UL, CSA, IEC, CE, and CCC certified unit features two interlocked contactors, 3 independent poles, coil-isolated main contacts, and operates at 50-60 Hz. It's designed for panel or 35mm DIN Rail mounting, operating between -25 and 60C up to 2000m altitude. Equipped with surge suppressors, electronic timers, mechanical interlocks, and IP 2X finger protection, it supports optional overload relays and offers space-saving coil terminations and pneumatic timing modules. Avoid heat and EMC noise exposure.
Is Your Device Showing These Signs?
The Allen Bradley 104-M12NKD31 commonly experiences issues such as nuisance tripping due to incorrect overload settings or thermal overload relay malfunction. Contactor coil failure, resulting in the inability to energize the motor starter, is a frequent problem. Auxiliary contact block damage or misalignment prevents proper signaling and control circuit operation. Inspect and replace worn or damaged contacts to address contact erosion and welding, which cause motor starting failures. Diagnose and resolve communication errors stemming from faulty DeviceNet connectivity or corrupted EDS files. Verify proper voltage and current levels to prevent premature component failure and ensure optimal performance.

Our Repair Process for the
104-M12NKD31
Our repair process for the Allen Bradley 104-M12NKD31 begins with a thorough inspection of the overload settings and thermal overload relay to eliminate nuisance tripping. We then assess the contactor coil, replacing it if it fails to energize the motor starter. The auxiliary contact block is examined for damage or misalignment, and corrected to guarantee proper signaling. Contact erosion and welding are addressed through meticulous inspection and replacement of worn or damaged contacts. DeviceNet connectivity is diagnosed to resolve communication errors, including verification of EDS files. Finally, voltage and current levels are verified to prevent component failure and ensure optimal performance.
