How Does an RCCB Work? | Residual Current Circuit Breaker 3D Animation

How does a Residual Current Circuit Breaker (RCCB) detect earth leakage and disconnect an electrical circuit? Explore the working principle of an RCCB through an educational 3D animation. This demonstration explains how the phase and neutral currents pass through a differential current transformer, how residual current creates a magnetic imbalance, and how the tripping mechanism disconnects the circuit. Learn the important differences between RCCB, MCB and RCBO protection. An RCCB provides residual-current protection but does not independently provide overload or short-circuit protection. This video uses illustrative models for educational purposes. Actual device construction and operating characteristics depend on manufacturer specifications and applicable electrical standards.
