In today's modern electrical systems, safety has become paramount. With the increasing use of electrical appliances and equipment in our daily lives, the need for effective electrical protection measures has become imperative. Among these, the Residual Current Circuit Breaker with Overcurrent Protection (RCCB) plays a crucial role in ensuring the safety of individuals and electrical infrastructure.

    The RCCB, as an advanced electrical safety device, combines the functionalities of a Residual Current Device (RCD) and a Miniature Circuit Breaker (MCB). It is designed to detect any imbalance in the current flowing through the circuit and, in the event of a fault, such as a leakage current or an electrical short, it immediately trips the circuit, disconnecting the power supply. This rapid disconnection helps prevent potential electrical hazards, such as electric shock or fire, from occurring.
