Since on some models the circuit breakers themselves turn back on after being turned off, in the event of an overload in the circuit, the turned off switch will turn off the circuit for a moment, and then return it to working condition. If the switch does not turn back on, check the electrical circuit immediately. Do not forget, however, that some circuit breakers must be manually reset after tripping.
After removing the source of the fault in the circuit, the circuit breaker will operate normally.
