    Function of RCCB

    Ground Fault Protection: RCCBs are specifically designed to provide protection against ground faults by detecting and interrupting current leakage to the ground. This function is crucial in preventing electric shock and ensuring the safety of individuals working with or around electrical equipment.
    Sensitivity Adjustment: Some RCCBs are equipped with adjustable sensitivity settings, allowing users to customize the device’s response to leakage currents. This feature enables the RCCB to cater to specific applications and environments where different levels of sensitivity may be required.
