  • and interrupts an abnormal current flow in a circuit. It is designed to protect people from electrical shock hazards by quickly disconnecting power when it detects a current leakage. Features: RCCB has a high sensitivity to current leakage and can detect even small imbalances in the current flow. It is also able to trip even when the fault current is lower than the magnetic trip current of a traditional circuit breaker. RCCB can be used in both single-phase and three-phase systems. Applications: RCCB is widely used in residential, commercial and industrial settings, especially in areas where electrical machines, tools or appliances are in use. It is typically installed at the main distribution board and may provide protection to specific circuits or devices. Overall, RCCB is an important safety device that helps prevent electrical accidents and ensures the safety of people and equipment.
