Product Description
The Allen-Bradley/Rockwell Automation 104-E146ED22 is a 3-pole reversing contactor from the Bulletin 104-E series, designed for AC and DC voltage applications. It features 3 normally open main contacts, 1 normally open auxiliary contact, and 1 normally closed auxiliary contact. Suitable for AC-1, AC-2, and AC-3 motors, it handles up to 146 Amps at 400V AC-3 (140F) or 225 Amps at 690V AC-1 (104F). When mechanically interlocked with another contactor, its dimensions are approximately 6 x 7 x 5 inches. It uses a standard 100-250V AC/DC electronic coil (50-60 Hz) and is also available with a PLC-compatible coil for logic-controlled applications.
Is Your Device Showing These Signs?
The Allen Bradley 104-E146ED22 commonly experiences issues such as contact degradation leading to operational failure, coil burnout due to overvoltage or inrush current, and mechanical wear affecting armature movement.
