May contain some.

The arc sensor 311 monitors the arc discharge by setting it as an accident event. Arc is generated in an insulator and is a generic term for a discharge phenomenon in which light is continuously emitted with burnout of an electrode. Since most arc-type defects accompany fire, when an event of arcing occurs, an arc breaker that immediately cuts off the current in the circuit is configured to operate.
