Circuit breaker open and closed
WebFrame – Protects internal parts of the circuit breaker from outside materials. Operating mechanism – Provides a means of opening and closing the circuit breaker. Contacts – Allows the current to flow through the circuit breaker when closed. Arc extinguisher – Extinguishes an arc when the circuit breaker interrupts a fault. WebIt engages when the circuit breaker is manually closed. This series combination prevents the reclosing relay from recognizing the open position of the circuit breaker when it is manually tripped, and permits the reclosing relay to reclose the circuit breaker automatically when it trips for a fault following a manual closure.
