3. Working principle

Explosion proof thermistor utilizes the principle of gap explosion-proof to design junction boxes and other components with sufficient strength. All components that can generate sparks, arcs, and dangerous temperatures are sealed inside the junction box cavity. When an explosion occurs inside the cavity, it can be extinguished and cooled through the gap between the joint surfaces, preventing the flame and temperature after the explosion from being transmitted outside the cavity, thus achieving explosion-proof.
