[Production Achievements] Preventing electrical fires! ◆ Generating significant interruption power with minimal force.
This is an earthquake-induced fire prevention device called a "sensitivity breaker." When an earthquake occurs, it automatically shuts off the breaker to prevent electrical fires after power restoration. A significant force is required to trip the breaker. However, the power from dry batteries cannot provide enough force to directly cut the breaker. Therefore, the breaker is tripped using a powerful spring, and the trigger's rotation initiates the spring's movement, allowing a small force (in this case, a small motor) to generate a large tripping force. *For more details, please refer to the PDF document or feel free to contact us.*

basic information
◆Background of Introduction More than 60% of the causes of fires during the Great Hanshin-Awaji Earthquake and the Great East Japan Earthquake were due to electrical fires. The 【Seismic Breaker】, which automatically shuts off the breaker during an earthquake, is an effective disaster prevention device that helps prevent large-scale disasters caused by electrical fires. ◆Solution There are various methods to shut off the breaker, but this time we are using a small motor to indirectly disconnect the breaker. A significant amount of force is required to disconnect the breaker, and it cannot operate on the minimal power of dry batteries. Therefore, the disconnection of the breaker is achieved using a powerful spring. The trigger for the spring to compress is activated by rotating it with a small motor. This allows a small motor to generate a large disconnection force while simultaneously saving power from the dry batteries. After operation, the spring and trigger can be reset to their original positions by operating a reset lever. ◆Effect When the sensor detects shaking equivalent to a seismic intensity of 5, the trigger is released, allowing for stable disconnection of the breaker. *For more details, please refer to the PDF document or feel free to contact us.
