TASK 610. TIME-CURRENT STUDY OF FUSES
Abstract
A study was made to evaluate electrical fuses used by the military services and to accurately classify them according to their blowing characteristics. Fuses were chosen from 3 major fuse manufacturers. The types and ratings of fuses most in use by the military were determined by contacting these manufacturers. The types decided upon were FO1, FO2, FO3, FO9, F10, and F11 - in both normal-blowing and time-lag fuses. Fuses were blown at currents of 110, 135, 150, 200, and 300% of their rated value. Time-current curves of every type and rating of each manufacturer were drawn. From these the range of blowing-time characteristics of each fuse type was determined. From this information recommendations were made for specifying blowing times of each type of fuse at various loads in order to more accurately distinguish between a normal and a time-lag characteristic.
