CAL3-40S Electro type RCBO is mainly used for AC 50Hz or 60Hz, rated voltage 230V or below and rated working current 40A or below and immediately cut off power supply once someone suffers from electric shock or leakage current above specified value. The circuit-breaker can also function as overload and short-circuit protection and unfrequented changeover of line under normal condition.
