Summary:

Revision of IEEE Std C37.40-1993 and C37.40b-1996. Superseded by IEEE C37.41-2016. Service conditions and definitions for high-voltage fuses (above 1000 V), distribution enclosed single-pole air switches, fuse disconnecting switches, and accessories for ac distribution systems are covered. These include enclosed, open, and open-link types of distribution cutouts and fuses; distribution current-limiting fuses; distribution enclosed single-pole air switches; power fuses, including current-limiting types; outdoor and indoor fuse disconnecting switches; fuse supports, mountings, switch sticks, and links, all of the type used exclusively with the above; and removable switch blades for certain products among the above. Scope: This project will add new definitions and revise existing definitions to bring the document up to date. Altitude correction factors will be revised to reflect the recommendations of the Switchgear Committee "Common Clauses" working group. Standard C37.40b, definitions for Capacitor Fuses, will be incorporated into the new document. Purpose: Changes have been made to other C37 High-Voltage fuse standards, and the definitions listed in C37.40 need to be modified to reflect these changes. The present C37.40 is experiencing difficulty in being re-affirmed due to a disagreement over the altitude correction factors. Because C37.40 is essential to the other documents (it contains the temperature rise requirements that they use) changes to the altitude correction factors may be needed to keep the standard in print.
