DPN RCBO residual current operated circuit breakers are suitable for purposes of residual current protection, overload and short circuit protection. When any personal electric shock occurs or the circuit leakage current exceeds the predetermined value, the residual current operated circuit breaker can automatically cut off the power supply in a very short period of time, so that the safety of persons and electrical equipment can be protected. . . . . . . . #powersupply #power #powerelectronics #
