By incorporating an earthquake detection function into the breaker, we achieve space-saving and cost reduction. A preventive measure against electrical fires caused by earthquakes!
There are two types of electrical fires caused by earthquakes: "fires immediately after the earthquake" and "restoration fires." By installing a seismic breaker that automatically turns off electricity upon detecting seismic tremors, we can prevent electrical fires caused by earthquakes. Nitto Kohki's "Seismic Breaker" is a product that achieves space-saving and cost reduction by integrating seismic detection functions into the breaker. It can also be retrofitted to existing distribution boards, making it suitable for both new and existing properties. 【Features of this product】 ● Space-saving and cost reduction achieved by integrating seismic relay and breaker. ● Notification display for seismic detection. ● Switchable cutoff time. ● Uses a 3-axis accelerometer for the seismic sensor. *For more details about the product, please feel free to contact us.

basic information
【Seismic Sensing Function】 ● When seismic waves equivalent to a seismic intensity of 5 strong or higher are detected, the power indicator lamp will blink and a buzzer will sound for a set period of time, after which the seismic breaker will automatically shut off. ● If a power outage occurs between the detection of seismic waves and the automatic shutoff, the seismic breaker will automatically shut off when power is restored. ● If seismic waves are detected within 8 seconds after a power outage, the seismic breaker will automatically shut off when power is restored. 【Reset Function】 ● If the reset button is pressed between the detection of seismic waves and the automatic shutoff of the seismic breaker, the blinking of the power indicator lamp, the sounding of the buzzer, and the automatic shutoff will stop, returning to the initial state. 【Test Function】 ● Pressing the test button will cause the seismic breaker to automatically shut off after a set period of time.
