The YCB7LE-63Y RCBO is a low-voltage protective device combining residual current protection (earth leakage protection) and overcurrent protection (overload and short circuit) within a single unit. Designed for AC systems, it provides protection against electric shock, earth fault currents, overload, and short-circuit conditions.
The device is suitable for residential, commercial, and light industrial applications and complies with IEC 61009-1 standards for RCBO devices.
