-In order to prevent damage, each station along the network is protected with circuit breakers or fuses which will turn off power in the event of a short circuit. 

- Auto Recloser is a circuit breaker equipped with a mechanism that can automatically close the breaker after it has been opened due to a fault. ---

- Reclosers are used on overhead distribution systems to detect and interrupt momentary faults. 

-The control system for a recloser allows a selected number of attempts to restore service after adjustable time delays. 

-For example a recloser have 3 "fast" reclose operations with a few seconds delay, then a longer delay and one reclose; if the last attempt is not successful, the recloser will lock out and require human intervention to reset.
