By incorporating seismic sensing functionality into the breaker, space-saving and cost reduction are achieved. 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 an earthquake-sensitive breaker that detects seismic tremors and automatically turns off the electricity, we can prevent electrical fires caused by earthquakes. Nitto Kohki's "earthquake-sensitive breaker" is a product that achieves space-saving and cost reduction by integrating earthquake detection functionality 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 the earthquake detection relay and breaker. ● Notification display for earthquake detection. ● Switchable cutoff time. ● Uses a 3-axis accelerometer for the earthquake 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 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 during the time from seismic wave detection to automatic shutdown, 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 during the time from seismic wave detection to automatic shutdown of the seismic breaker, the blinking of the power indicator lamp, the sounding of the buzzer, and the automatic shutdown 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.
