Description
RCCB 3 Phase Residual Current Circuit Breaker is applicable to electric circuits with rated voltage 230/400V AC, frequency 50/60Hz and rated current up to 125Amp.
RCCB 3 Phase‘s main function is to provide indirect protection to the operator’s body under the condition of exposing live parts. It should be connected to an appropriate grounding electrode.
In addition, the RCCB 3 also provides protection against fire hazards due to ground fault current caused by the malfunction of the overcurrent protection device.
It can effectively reduce hidden circuit hazards and is an indispensable protective device in households and industries.
RCCB 3 Phase 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. 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.
3. RCCB provides on protection against electric shock resulted from direct contacts of both protected lines,or leakage current between these two lines.
4.RCCB designed for household installation and other similar application, is for non-professional operation, and no maintenance is required.
5. Satisfying conditions and applications as mentioned above,RCCB with “ON-OFF” indicating device is considered suitable for isolation function.
