    Advantage of AC RCCB


    Function of RCD Residual Current Device

    1. RCCB with rated sensitivity up to 10mA could be used as supplementary protecting device in case other protecting device fails its protection against electric shock.
    2. RCCB designed for household installation and other similar application, is for non-professional operation,and no maintenance is required.
    3. RCCB provides on protection against electric shock resulted from direct contacts of both protected lines,or leakage current between these two lines.
    4. Particular devices such as surge protective devices,surge arrester etc are recommended to install at upstream line to RCCB as precaution against potential surge voltage and current occurring at its power input side.
    5. Satisfying conditions and applications as mentioned above,RCCB with “ON-OFF” indicating device is considered suitable for isolation function.
