Motor Starting: It houses a built-in capacitor (35μF, as indicated on the label) that provides the necessary electrical boost to start the pump's motor.System Protection: It features an integrated thermal overload circuit breaker (10A rating) that automatically disconnects power if the pump overheats or experiences an electrical surge, preventing motor burnout.Operational Control: It acts as the central interface for the pump, typically including an ON/OFF switch and a manual reset button for the protector.
