GFN Series / Indicating Time Delay Fuse
The GFN Series / Indicating Time Delay Fuse is part of the Mersen (formerly Ferraz Shawmut) general purpose fuses line, distributed by Gross Automation.
GFN midget indicating fuses are available in 34 ratings from 1/10A through 30A. These time-delay fuses have built-in blown fuse indicators which pop out at the end of the fuse to visually indicate when the fuse has operated to open the circuit. Indicators may be used to trip a switch for remote as well as visual annunciation. (Not for Branch Circuit Protection).
