Allen-Bradley 810-A16C AC Coil Relay Contactor

The Allen-Bradley 810-A16C is an inverse-time current relay from the 810-A family, designed to be used with a control contactor in motor-protection schemes; it monitors line current, compares it to calibrated thresholds, and delivers a time-delayed trip signal when overload or fault conditions exceed preset levels, enabling selective coordination that protects both the motor and driven equipment in industrial electrical systems, while supporting fast, predictable shutdown that minimizes electrical noise and mechanical wear. With a coil current rating of 100 A, the 810-A16C defines the operating range for overload sensing and provides the timing behavior characteristic of inverse-time relays, a staple in motor protection applications. Manufactured by Allen-Bradley (Rockwell Automation), these relays are commonly kept in stock in industrial catalogs and are used with compatible 810-A contactors to deliver reliable protection for motors in conveyors, pumps, fans, and other automation equipment.
