Allen-Bradley 810-1RP Magnetic Overload Relay

Allen-Bradley 810-1RP Magnetic Overload Relay is a magnetically operated overload protection device in the Allen-Bradley Bulletin 810 family, identified by model 810-1RP (8101RP) and order code B689559/3. Designed to be used with a compatible Allen-Bradley contactor, the relay monitors current in the motor circuit and interrupts power to the coil when an overload condition is detected, guarding the connected motor from overheating and potential damage. This compact protective relay is intended for industrial motor-control applications where reliable motor protection is required in starter assemblies; it is commonly paired with Allen-Bradley motor starters to form a compact, integrated protection scheme for AC motors across conveyors, pumps, fans, and other machinery. The 810-1RP designation denotes a single relay within the 810 family; when replacing or sourcing compatible devices, order the variant that matches your existing equipment and refer to the B689559/3 variant to ensure proper fit and electrical compatibility with your control panel. Buyers should verify compatibility with their current 810-series starters, confirm coil voltage and mounting/terminal requirements, and confirm the device’s operating envelope with their motor's horsepower and voltage class to ensure reliable protection in their specific application.
