Allen-Bradley 809-A01E Relay

Allen-Bradley 809-A01E Instantaneous Trip Current Relay delivers fast overcurrent protection for industrial control circuits by tripping immediately when the sensed current exceeds a user-adjustable threshold. It is rated for a maximum of 600 V AC/DC and supports a continuous coil current of 2 A, with the tripping current adjustable in AC operation from 1.1 to 3.1 A and in DC operation from 0.95 to 2.8 A. As part of Allen-Bradley’s protection relays, this Series A unit is commonly used in motor control panels, feeder protection, and protection schemes where immediate response to overloads is required. The device is designed to drive a trip signal to a contactor coil or protective device, enabling rapid isolation of faulty loads, and its rugged construction accommodates typical industrial environments while fitting within standard Allen-Bradley control-system layouts.
