MS30LE-32Residual Current Operated Circuit Breakerwith Over-currentProtection (Earth LeakageCircuit Breakerwith OverCurrentProtection)

  • The RCBO combined MCB&RCCB is used in the single phase circuit of AC 50Hz/60Hz, rated voltage 230V, used as electron shock protection. It can protect circuit form overload and short circuit. This product has advantages of small volume, high breaking capacity, live and zero wire are cut off at the same time, also protecting person from electric shock when the live wire connected opposite. It conforms with the standards of IEC61009.
