Superseded Standard

IEEE/ASA C37.4thru9-1945

ASA American Standards for Alternating Current Power Circuit Breakers

This publication represents standard practices in the United States relating to alternating-current power circuit breakers. It contains data secured from many sources notably the established standards of the American Institute of Electrical Engineers and the National Electrical Manufacturers Association. It also includes data prepared by the Association of Edison Illuminating Companies. This publication combines, in one reference work, information relating to the terms and conditions upon which the rating and behavior of alternating-current power circuit breakers are based. The publication is divided into six parts. The main part consists of a definite Standard, C37.4-1945, for alternating-current power circuit breakers, which covers definitions and ratings of apparatus coming within the scope of this work. The remainder consists of supplementary standards, one of which, C37.9-1945, covers the procedure for testing circuit breakers. The Schedule of Preferred Ratings for Indoor and Outdoor Circuit Breakers, C37.6-1945, is included.

No Active Projects

Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.


No Active Standards

These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.


No Superseded Standards

These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.


No Inactive-Withdrawn Standards

These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
