PROBLEM TO BE SOLVED: To provide a distribution board with a seismic shutdown function that allows a plurality of electric leakage breakers to be cut-off by one seismic relay.;SOLUTION: A distribution board with a seismic shutdown function comprises: a trunk electrical leakage breaker 1 to which a lead-in line of a single phase three-line type cable type A is connected; a plurality of branched breakers 2 that is connected to a secondary side cable way A2 of the trunk electrical leakage breaker 1; a seismic relay 4 used for sensing and shutting-down the trunk electrical leakage breaker 1 when an earthquake exceeding a specific earthquake intensity is sensed; and a branched electric leakage breaker 3 that is connected to a primary side of the trunk electrical leakage breaker 1, and forms a primary feeding circuit C. The seismic relay 4 is connected between a secondary side neutral phase N of the trunk electrical leakage breaker 1 and one voltage phase L2 of the secondary side of the branched electric leakage breaker 3 that forms the primary feeding circuit C.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
