C37.27-2024
IEEE Guide for Low-Voltage AC (635 V and below) Power Circuit Breakers Applied with Separately-Mounted Current-Limiting Fuses
Application recommendations to assist in selection of separately mounted current-limiting fuses to be installed in series with low-voltage ac power circuit breakers are provided in this guide.
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.
C37.27-1987
IEEE Standard Application Guide for Low-Voltage AC Nonintegrally Fused Power Circuit Breakers (Using Separately Mounted Current-Limiting Fuses)
Low-voltage power circuit breakers of the 600 V insulation class with separately mounted current-limiting fuses, for use on ac circuits with available short-circuit current of 200 000 A (rms symmetrical) or less, are covered. Guidance is provided respecting coordination of circuit breaker and fuse, location of fuses, open fuse trip devices, addition of fuses to existing installations, protection of connected equipment, and tested combinations of circuit breakers and fuses.
C37.27-2008
IEEE Application Guide for Low-Voltage AC Power Circuit Breakers Applied with Separately-Mounted Current-Limiting Fuses
Information to assist in selection of current-limiting fuses for use with low-voltage ac power circuit breakers with separately mounted current-limiting fuses is provided.
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No Inactive-Withdrawn Standards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.
No Inactive-Reserved Standards
