YCB3RL-63 series electromagnetic residual current operated circuit breaker is mainly suitable for AC distribution networks with a rated working voltage of 230V or 400V at 50/60Hz and a rated current of 63A. Used for indirect contact protection of people, and can also be used to prevent fire hazards caused by insulation damage to circuits and equipment,resulting in ground fault currents.
1. Protection against the effects of sinusoidal alternating earth fault currents.
2. The leakage protection feature does not require an auxiliary power supply.
3. Not affected by voltage fluctuations in the power grid.
