RCCB 63A 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 an appropriate ground electrode.
In addition, it also provides protection against fire hazards due to ground fault current caused by the malfunction of the overcurrent protection device.
Because of its stability and the advantages of effectively reducing the hidden dangers of electricity use, it can meet the application of most scenarios.
RCCB 63A Special tips:
1. The RCCB with a rated sensitivity of up to 30mA can be used as an auxiliary protection device to prevent other
the protection device cannot prevent electric shock.
2. RCCB provides protection against electric shock caused by direct contact between two protected circuits, or leakage current between these two wires.
3. It is recommended to install special devices on the upstream line of the RCCB, such as surge protectors, lightning arresters, etc.
To prevent potential surge voltage and current from appearing on the power input side.
4. In order to meet the above conditions and applications, RCCB with “ON-OFF” indicating device is considered suitable for isolation function.
