The CNC YCB6HLE-63 is a 3P+N RCCB, which is a safety device that protects against electrical leakage (residual current) and overcurrents. It's designed to quickly cut off power to prevent electric shock and fire hazards. The "3P+N" configuration means it's used in three-phase electrical systems and includes a neutral connection. It's a combination device, providing both RCCB and circuit breaker functions in one unit.
