The Schneider Electric EZ7 RCBO is a Residual Current Circuit Breaker with Overcurrent Protection designed for DIN-rail mounting. It combines overcurrent protection (like a miniature circuit breaker) and residual current (earth leakage) protection in a single compact modular device. It is used in electrical distribution systems to protect circuits from overload, short-circuit, and earth leakage current faults, improving safety for people and electrical installations.
