The invention discloses a 400V low-voltage switch frequent tripping judgment instrument, and relates to the technical field of power distribution equipment. A current detection module is used for collecting the current of a power transmission cable passing through a transformer, and a voltage detection module is used for collecting the voltage of the power transmission cable passing through the transformer; the signal processing module is used for conditioning the current and the voltage transmitted by the current detection module and the voltage detection module, and the MCU control module is used for carrying out load calculation according to the voltage and the current processed by the signal processing module; the display module displays the load data calculated by the MCU, and a first-aid repair worker judges whether tripping occurs or not according to the instantaneous voltage and current conditions, displayed and recorded by the display module, of low-voltage tripping of the transformer, so that the tr
