IEEE C37.27
Application Guide for Low-Voltage AC non-integrally fused power Circuit Breakers (using Separately-Mounted Current-Limiting Fuses)
| Organization: | IEEE |
| Publication Date: | 28 July 1972 |
| Status: | inactive |
| Page Count: | 13 |
scope:
This guide applies to low-voltage power circuit breakers of the 600-voIt insulation class with separately mounted current-limiting Class J and Class L fuses for use on ac circuits with available short-circuit currents of 200 000 amperes (rms symmetrical) or less.
Low-voltage integrally fused power circuit breakers (see American National Standard Low-Voltage A C Integrally Fused Power Circuit Breakers, C37.28-1969) and combinations of fuses and molded-case circuit breakers are not covered by this guide.
Purpose
This guide sets forth recommendations believed essential for the selection of Class J and Class L current-limiting fuses meeting N E M A Standard on Low-Voltage Fuses, FU 1-1966, and American National Standard Low-Voltage Cartridge Fuses 600 Volts or Less, C97.1- 1972, for use in combination with low-voltage power circuit breakers, rated in accordance with American National Standard Low-Voltage A C Power Circuit Breakers (600-Volt Insulation Class) C37.13-1963.
