Product Description

The Allen-Bradley 100-D420-VT kit is an accessory for MCS contactors, specifically designed for Allen-Bradley Bulletin 100-D and 100S-D contactors (especially 100-D210 to 100-D420 non-reversing models). It facilitates reversing output and Wye-Delta connections for starting 3-phase AC motors, requiring UL/CSA-compliant copper frame terminal lugs (with "100-DL" in the part number). This kit, part of a comprehensive range of Bulletin 100-D accessories, supports conductors up to 120 sq mm and enables customization for specific applications, offering power ratings up to 250 HP at 200V, 600 HP at 460V, and 650 HP at 575V (60 Hz) in Wye-Delta configurations.

Is Your Device Showing These Signs?

The Allen Bradley 100-D420-VT commonly experiences issues such as coil failures due to voltage fluctuations or overheating, resulting in contactor malfunction. Terminal block damage from improper torque during wiring is a frequent problem, leading to loose connections and potential arcing. Overload relay tripping caused by excessive motor current draw or incorrect FLA settings requires investigation and adjustment. Contactor contact erosion from repetitive switching or high inrush currents reduces conductivity and necessitates replacement. Auxiliary contact block failures impact signaling and control circuits, demanding inspection and potential replacement of the auxiliary module.

Technical specifications

  • The Allen-Bradley 100-D420-VT kit is an accessory for Allen-Bradley Bulletin 100-D and 100S-D contactors (specifically 100-D210 to 100-D420 non-reversing models) that enables reversing output and Wye-Delta connections for starting 3-phase AC motors. It requires specific UL/CSA-compliant copper frame terminal lugs and supports conductors up to 120 sq mm, offering power ratings up to 650 HP depending on voltage and configuration.

Our Repair Process for the

100-D420-VT

Our repair process for the Allen Bradley 100-D420-VT begins with a comprehensive inspection to diagnose coil failures, terminal block damage, overload relay tripping, contactor contact erosion, and auxiliary contact block failures. Coil failures are addressed by replacing the coil and implementing voltage regulation measures. Damaged terminal blocks are replaced, and proper torque specifications are enforced during re-wiring. Overload relay tripping requires investigation of motor current draw and FLA settings, with necessary adjustments made. Contact erosion necessitates contactor replacement to restore conductivity. Auxiliary contact block failures result in module replacement to ensure proper signaling and control circuit functionality.
