| time. The same cycle is repeated for a third reclosure after a time interval that is usually somewhat longer than that for the first two reclosures. If, upon the third reclosure, the fault persists, the breaker opens again automatically and remains open or locked out. The purpose of this reclosing cycle of operations is to restore to service as quickly as possible any circuits that may be temporarily faulted because of lightning, wires temporarily crossed by tree limbs or wind, or other causes of a temporary or transient nature. |

| The reclosers consist of a small motor actuated by the initial tripping of the breaker. When the overcurrent relay contacts make contact, the tripping circuit of the breaker is completed and the breaker opens. At the same time, an auxiliary switch on the breaker starts a small motor that, through a train of gears, moves a disc or drum on which the contacts are mounted. As these contacts make contact, the reclosing circuits controlling the operation of the breaker are completed. If the fault persists, the overcurrent relay again trips the breaker open. After a cycle of such operations, a final contact is opened to de-energize the recloser motor. |

| Succeeding reclosures are usually spaced at increasing intervals of time; a duty cycle of 01560-second intervals is common practice. |
