RCCB stands for Residual Current Circuit Breaker, which is an important safety device used in electrical systems. It is used to detect ground faults and personal electric shock risks, and block circuits to protect personnel safety.
2P and 4P represent two-pole and four-pole respectively, and are used to describe the connection method of the RCCB circuit breaker. 63A, 5A, 25A and 40A represent the rated current respectively.
