25A RCCB Residual Current Circuit Breaker is applicable to electric circuits with rated voltage 230/400V AC, frequency 50/60Hz and rated current up to 125Amp.
The RCCB provides indirect protection for the operator’s body when exposed live parts should be connected to an appropriate ground electrode.
25A RCCB Special tips:
1. The RCCB with a rated sensitivity of 30mA can be used as an auxiliary protective device to prevent other protective devices from failing.
2. RCCB designed for household installation and other similar application, is for non-professional operation, and no maintenance is required.
3. RCCB also provides protection against fire hazards
The ground fault current caused by the malfunction of the overcurrent protection device.
5. Satisfying conditions and applications as mentioned above,RCCB with “ON-OFF” indicating device is considered suitable for isolation function.
