Allen-Bradley 809-A09E Instantaneous Trip Current Relay is a magnetically operated device within Rockwell Automation’s Bulletin 809 motor protection family. It provides instantaneous overcurrent protection for motors and related circuits, tripping with no intentional delay when the current exceeds its set point. The model 809-A09E specifically carries a 28 A trip current rating, aligning with the A-series’ high-range instantaneous relays used in open-type motor protection configurations.
