    Residual Current Circuit Breaker (RCCB) and its Advantages and Functions

    Residual Current Circuit Breaker (RCCB) is a crucial electrical safety device that plays a significant role in protecting people and property from electrical hazards. It is designed to detect and interrupt abnormal current flows, such as leakage currents, which can occur when there is a fault in the electrical system. RCCBs are widely used in residential, commercial, and industrial settings to provide an additional layer of protection against electric shock and fire hazards. In this article, we will explore the advantages and functions of RCCBs, as well as their importance in ensuring electrical safety.
