ABSTRACT:
A device for quickly reconnecting two portions of a current carrying line after separation of the line portions through actuation of a circuit breaker includes a second circuit breaker and a serially connected switch connected in parallel with a primary circuit breaker. Closure of the switch reconnects the line portions through the second circuit breaker after actuation of the primary circuit breaker. The switch can include auxiliary contacts for supplying power to an ignition device associated with the second circuit breaker, to render the second circuit breaker operable only when the switch is closed.
