The product code 100-D420-VLTB is the product code for a connecting component kit that has been manufactured by Allen-Bradley/Rockwell Automation. This Bulletin 100-D series reversing input connector kit is intended for AC-powered compact contactors and starters. Besides input connector kits, other available accessories from the Allen-Bradley Bulletin 100-D series are output connector kits, Delta-Wye connector kits, power wiring kits, terminal lugs, control circuit terminals, terminal covers, terminal shields, interlocks, and mounting plates. The 100-D420-VLTB input connector kit works with the reversing contacts and it supports Wye-Delta connections, including main Delta connections. The output connection of the 100-D420-VLTB input connector kit is 120 square millimeters in area. Additionally, the 100-D420-VLTB reversing input connector kit is compatible with NEMA Size 5 components and it supports terminal blocks as its primary terminal connection hardware. The product code of the supported terminal connection hardware is “100-DTB.” 

In addition to the Allen-Bradley/Rockwell Automation 100-D420-VLTB Bulletin 100-D connector kit, the system can be upgraded with additional suppressor modules, marking systems, control modules, auxiliary contacts, and various assembly components. These components support multiple mounting options and they are available for devices with NEMA sizes from 0 to 5. Generally, the 100-D420-VLTB connector kit is intended for compact contactors that have been built with a space-saving design. These contactors use either electronic and conventional coils and they are mountable on 35-millimeter DIN Rails. The contactors and starters from the Bulletin 100-D line are compatible with solid-state overload relays and they feature guarded terminals. The supported motor voltage ranges are 200 Volts, 230 Volts, 380 to 415 Volts, and 460 to 575 Volts. These Allen-Bradley components are all manufactured in compliance with the UL 508, CSA C22.2 (No. 14), and NEMA EEMAC ICS2 standards.
