Seismic Breaker

Electrical Fires Caused by Earthquakes

It is said that about 60% of fires caused by earthquakes are due to electrical issues, such as fires from electrical equipment due to shaking and fires that occur when power is restored after a blackout.

One of the measures to prevent these fires is the "Seismic Breaker".

What is a seismic breaker?

The "earthquake breaker" is a device that automatically shuts off electricity, such as breakers and outlets, when it detects shaking above a set value during an earthquake. Installing an earthquake breaker is an effective means of preventing electrical fires in situations where you are not at home or do not have the time to turn off the breaker and evacuate.

Types of Earthquake Breakers

Distribution Board Type (Built-in)

The sensor built into the distribution board detects shaking and cuts off the breaker to stop the electricity. (Cost: approximately 50,000 to 80,000 yen)

Subpanel Type (Retrofit)

This is a type that adds an earthquake detection function externally to the distribution board, where a sensor detects shaking and cuts off the breaker to stop the electricity. (Cost: approximately 20,000 yen)

Outlet Type

The built-in sensor in the outlet detects vibrations and cuts off the electricity from the outlet. (Cost: Approximately 5,000 to 20,000 yen)

Simple Type

The breaker will be turned off to cut off the electricity due to the operation of the spring or the drop of the weight. (Cost: approximately 2,000 to 4,000 yen)

Points to Consider When Installing Earthquake Breakers

When installing an earthquake breaker, it is necessary to take measures to ensure that you are not inconvenienced if the electricity suddenly stops.

• If you have medical equipment that is directly related to sustaining life, please ensure that you are equipped with batteries or other means to deal with power outages.
• To ensure lighting at night, let's keep lighting equipment such as footlights and flashlights that operate during power outages on hand.
• Before restoring power, please confirm that there are no gas leaks and check the safety of electrical appliances.
• If you smell something burnt after the power is restored, immediately turn off the breaker, conduct a safety check again, and if the cause is unknown, it is necessary to refrain from using electricity.
• Let's regularly check the operational performance and replace parts as necessary.
