General
RCBO is mainly used for AC 50Hz (60Hz), rated voltage 110/220V, 120/240V, rated current 6A to 40A low-voltage terminal power distribution system, RCBO is equivalent to MCB+RCD function; used for electric shock protection and personal injury indirect contact protection, Protection of electrical equipment, overload and short-circuit protection when the human body gets an electric shock or the leakage current of the power grid exceeds the specified value; it can also be used as a non-frequency operator in the circuit, widely used in residential and commercial areas. It conforms to the IEC61009-1 standard.
