    Advantages of RCCB

    Easy Installation and Maintenance: RCCBs are relatively easy to install and require minimal maintenance. Once installed, they continuously monitor the electrical system for abnormal currents and provide reliable protection without the need for frequent adjustments or servicing.

    Current Sensing: The primary function of an RCCB is to sense the difference between the incoming and outgoing currents in a circuit. When the device detects a mismatch, it indicates the presence of a leakage current, which could be caused by a fault or an unintended path for current flow.
    Tripping Mechanism: Upon detecting a leakage current, the RCCB activates its tripping mechanism to quickly disconnect the circuit. This action helps prevent electric shock and other hazards associated with abnormal current flows.
