Allen-Bradley 815-B0V16 Relay

Allen-Bradley 815-B0V16 Relay is a three-pole overload relay in Rockwell Automation's 815-series, designed to protect 3‑phase motors in industrial control circuits. This unit functions as the motor overload protection element in a typical Allen‑Bradley contactor assembly, tripping to disconnect the motor if current exceeds its preset threshold, thereby reducing the risk of winding damage and overheating. Marketed as a Series K overload relay, the 815-B0V16 carries a 27 A current rating, making it appropriate for medium-load motor applications across conveyors, pumps, fans, and other automation equipment that rely on Rockwell components. Used alongside compatible Rockwell/Allen‑Bradley contactors and protection devices, it integrates into standard motor control schemes found in manufacturing and processing facilities. The model designation identifies it as part of the 815 family, a legacy line that remains a common replacement part for existing installations, ensuring continued motor protection for older equipment.
