Mersen GFN Midget Time-Delay Fuse, 250VAC Ferrule

Mersen GFN Midget Time-Delay Fuse, 250VAC Ferrule

The Mersen GFN Midget Time-Delay Fuse is a 250VAC, Ferrule-terminal fuse built with a built-in blown-fuse indicator that pops out at the end of the fuse to give visual confirmation when the fuse has operated. This GFN indicating fuse series is available in 34 ratings from 1/10A through 30A, and the indicator can also be used to trip a switch for remote signaling as well as visual indication. As a Time-Delay, Midget-class fuse rated AC at 50/60Hz, it is intended for supplemental overcurrent protection and is not for Branch Circuit Protection.

Key Features

• Wide Rating Range: Available in 34 ratings from 1/10A through 30A to cover a broad range of circuit protection needs.
• Time-Delay Characteristic: Time-Delay speed rating allows the fuse to ride through momentary current surges without nuisance operation.
• Ferrule Termination: Ferrule connection/terminal type with Tin-Plated Copper terminal material for a reliable clip-mount fit.
• Visual Indicator: Built-in blown fuse indicator pops out at the end of the fuse when it has operated, and can also trip a switch for remote indication.
• Voltage & Frequency: Rated 250 V AC at 50/60 Hz for standard AC circuit applications.
• Clip Mounting: Midget fuse class designed for clip mounting in compatible fuse holders and blocks.
• Body Construction: PolyTube body/insulating material for the fuse housing.
