RCCB 63A 30mA Residual Current Circuit Breaker is applicable to electric circuits with rated voltage 230/400V AC, frequency 50/60Hz and rated current up to 125Amp.
Its working principle is to provide indirect protection to the operator’s body under the condition of exposing live parts. It should be connected to the correct ground electrode.
RCCB 63A 30mA Special tips:
1. RCCB with rated sensitivity up to 30mA could be used as supplementary protecting device in case other protecting device fails its protection against electric shock.
2. RCCB provides protection against the fire danger caused
by earth fault current due to function failure of over-current protection device.
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.
