Miniature RCBO

Residual Current Breaker with Overcurrent.

MExcel series Residual Current Breaker with Overcurrent is mainly used in AC 50Hz with rated working voltage 230V and with rated current up to 40A. In case of personal electric shock or when the grid leakage current exceeds the specified value, the RCBO can work to quickly cut off the power supply within the very short time for protection of the safety of personnel and electrical equipment.

Suitable for industrial, commercial and domestic installations.
