Rated Reclosing Time. The rated reclosingtime of a circuit breaker is the shortest reclosing time which the breaker is required tomeet with rated control voltage and ratedfluid operating pressure applied.

Short-Circuit Rating. The short-circuitrating of a circuit breaker is established by thesymmetrical component of short-circuitcurrent in rms amperes,designated rated short-circuit current,to which all requiredshort-circuit capabilities are related.

All valuesapply to both grounded and ungroundedshort circuits on predominantly inductive orresistive3-phase circuits witha normalfrequency phase-to-phase recovery:: voltageequal to the operating voltage. Download infomation Go to download. Some ratings have also been updated.

Because this revision is primarily editorial in nature, this Foreword describes the substantive and editorial changes between this revision and the version. The format of the tables remains very much the same, except that some ratings, which had been given in the notes sometimes on a different page from the table of preferred ratings , have been listed explicitly in the tables.
