In the need, setting of vibration sensing breaker
For the latest earthquake damage assumption (H24.10) of Yokohama-shi, the death tolls by fire largely increase from 1,548 personality, last damage assumption (H17.3).
And we are considered that (excluded for cause ignorance) is related to electricity 60% of cause of fire in past great earthquake disaster or more.
When strong earthquake occurred in Motoichi, fire from electric heat appliances, fire from electric cords snapped at electric restoration again are expected.
With vibration sensing breaker
It is effective to intercept breaker at the time of evacuation to prevent electric fire. However, we may not get such an action at the time of major earthquake occurrence at once.
Vibration sensing breaker is effective appliance which senses shaking of earthquake that is higher than set point, and interrupts electric supply automatically, and prevents electric fire. We prevent fire by installing in each family, and it is thought that by preventing spread of fire to other houses, can greatly reduce damage.
About type of vibration sensing breaker
Vibration sensing breaker has thing of the following type mainly.
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.
We install vibration sensing sensor in switchboard.
We connect vibration sensing sensor to switchboard.
When we are connected to switch of switchboard of home, and sensed shaking, we drop switch by fall of weight ball or action of spring and cut off electricity of all in house. A lot of relatively cheap things do not need construction.
There are types (construction required) to exchange for type to insert in outlet of home and existing outlet, and to bury. Setting to point to connect electric heat appliances such as electric heater or heater for appreciation fish to is suitable basically to interrupt electricity of individual outlet.
About assistance to vibration sensing breaker
In Yokohama-shi, we support the purchase, installation of vibration sensing breaker (simple type) for people living in "earthquake fire measures policy in Yokohama-shi earthquake disaster prevention strategy" prediction areas.
１．As for the vibration sensing breakers, it is setting promotion business subsidy

Instructions on installing
- Vibration sensing breaker is not available for all switchboards. Setting may be difficult by type of switchboard. When judgment is difficult, please refer to each manufacturer.
- When you install medical devices connected directly with maintenance of life, please comprise battery which can deal with blackout.
- Because it is thought, it will prepare for non-ever-burning light as light disappears when earthquake occurs in the night, to disturb quick and safe evacuation to the outdoors.
- Person living for lease, please install vibration sensing breaker after consultation with landlords to include the need of the current situation recovery duty.
- When it does power restoration after having done hatsuwazawai, when it feels, it cuts off breaker promptly, and it confirms smell that burnt safely again, and it is necessary that unidentified case stops electric use.
- After having installed vibration sensing breaker, let's change parts depending on confirmation and need of the periodical operation performance.
