The Allen-Bradley 809-A15E Instantaneous Trip Current Relay is a magnetically operated current relay from the Bulletin 809 family, designed for immediate overcurrent protection in AC or DC circuits. It supports up to 600 V AC/DC and is offered in a NEMA 1 open enclosure suitable for surface mounting in control panels. After a trip, the relay resets at a defined percentage of its trip setting—approximately 70–85% for AC operation and 62–82% for DC—providing reliable, repeatable reset behavior for motor protection and other overcurrent applications.
