The BRC1-F Series AC Contactor is suitable for circuits with AC 50Hz (60Hz), rated operating voltage up to 1,000V, and current from 115A to 800A. It is used for remote making and breaking of circuits and for frequent starting and control of AC motors. The contactor can be easily fitted with auxiliary contact blocks or pneumatic time-delay blocks and can be combined with appropriate thermal overload relays to form electromagnetic starters, thereby protecting circuits that may experience operational overload.
