Product Overview
The Allen-Bradley 100-D420EA00 is a high-current IEC power contactor from the Bulletin 100-D series, designed for demanding motor control and power switching applications in industrial automation. As a 420 Amp, 3-pole non-reversing contactor, the 100-D420EA00 serves as the critical final power-stage interface between PLC controllers and large inductive loads such as motors, pumps, compressors, and conveyors. The 100-D420EA00 belongs to Rockwell Automation’s MCS D (Motor Control System D) architecture, representing the highest-current tier of the Bulletin 100-D product line with ratings extending up to 860 Amps.
The defining characteristic of the 100-D420EA00 is its electronic coil with integrated electronic interface, designated by the “EA” code in the part number. Unlike conventional AC electromagnetic coils that draw high inrush current and sustain constant high holding power, the electronic coil of the 100-D420EA00 operates across a wide control-voltage range—208-277V AC at 50/60 Hz—while consuming significantly less power during operation. This low-power design enables direct connection to PLC digital output modules without requiring intermediate power amplifiers or interposing relays, simplifying control panel architecture and reducing heat generation within enclosures.
The 100-D420EA00 features three main power poles with no built-in auxiliary contacts (the “00” suffix), providing a clean foundation for engineers to add side-mounted auxiliary contact blocks as application requirements dictate. Its silver-alloy main contacts are rated for a breaking capacity of 8-10×Ie, ensuring reliable arc extinction under the heavy inductive loads characteristic of AC-3 motor starting duty. Although Rockwell Automation has discontinued the 100- (with the 100-E400ED11 designated as the engineering replacement), this contactor remains essential for the extensive installed base of Bulletin 100-D systems worldwide, preserving proven motor control infrastructure without costly redesign.
