This standard applies to all indoor and outdoor types of ac high-voltage circuit breakers rated above 1000 V and rated on a symmetrical current basis. Inconsistency in application of preferred ratings of high-voltage circuit breakers may result in wrong application of interrupting current and voltage levels. The recommendations outlined in the following clauses are intended to provide consistent functionality for high-voltage circuit breakers rated above 1000 V. New IEEE Standard - Superseded. Superseded by C37.04-2018. The preferred ratings of indoor and outdoor high-voltage circuit breakers rated above 1000 V for use in commercial, industrial, and utility installations are described in this standard.
