It is effective to intercept breaker at the time of refuge, but may not get such an action at the time of major earthquake occurrence at once to prevent electric fire.
Vibration sensing breaker interrupts electric supply at the time of earthquake occurrence of seismic intensity which is higher than set point automatically and prevents fire by installing in each home and can greatly reduce damage by preventing spread of fire to other houses

1.Switchboard type
All electricity is cut off with thing with function to sense constant seismic intensity, and to interrupt electricity basically by switchboard of home. At homes with medical appliances using electricity, attention is necessary about setting.
