Allen-Bradley 810-A26C Series-A Inverse Time Relay

The Allen-Bradley 810-A26C Series-A Inverse Time Relay is a high-current protective relay rated for up to 259 A and up to 600 V, designed to provide inverse-time overcurrent protection in industrial AC circuits. As part of Allen-Bradley's Bulletin 810 family, the Series-A model employs an inverse-time timing characteristic to coordinate tripping with other protection devices, allowing brief inrush currents to pass while interrupting sustained overloads. Typical applications include motor protection, feeder protection, and other electrical circuits requiring reliable, time-delayed response to overcurrent. The A26C designation identifies this specific Series-A variant within the 810 relay line, reflecting its 259 A / 600 V rating.
