RCCB Breakers

ETEK Solar RCCBs (Residual Current Circuit Breakers) detect earth leakage and residual fault currents to protect people from electric shock and reduce the risk of electrical fires. Installed in distribution boards, they continuously monitor the balance between live and neutral conductors and trip instantly when leakage exceeds the rated residual current.

Available in Type AC, Type A, and Type B, our RCCBs cover sensitivities of 10mA, 30mA, 100mA, and 300mA, with ratings from 16A to 100A. Type B RCCBs are especially suitable for solar inverters, EV charging stations, and frequency converters, as they detect smooth DC residual currents. Compliant with IEC/EN 61008-1, ETEK Solar RCCBs deliver high-sensitivity residual current protection for modern electrical installations.
