A multi-switch module of a smart distribution board equipped with a multi-switch module with high-precision digital technology according to the present invention for achieving the above object receives the current value of each phase detected by the CT, and receives any one of the three-phase current values. A CPU that outputs a trip signal when the current value of the clothing is higher than the set allowable current value; And a plurality of dip switch units connected to each of the main breaker and the plurality of branch breakers and capable of selecting different allowable current values through switch operation; including, the adoption of a dip switch improves the accuracy of the MCCB to within 2%, and It is easy to select load and instantaneous load, and there is an effect that 50% of the breaking capacity for sudden load monitoring can be easily selected.
