3 Phase RCCB Price 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 main function is to provide indirect protection to the operator’s body when exposed live parts should be connected to an appropriate ground electrode.
RCCB also provides protection against the fire danger caused by earth fault current due to function failure of over-current protection device.
3 Phase RCCB Price 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 is designed for home installation and other similar applications for non-professional operation, And no maintenance is required.
3. RCCB provides protection against electric shock caused by direct contact between two protected circuits, or leakage current between these two wires.
4. RCCB is designed for non-professional home installation and other similar applications. And no maintenance is required.
