Overview

The Mersen GGU8 (SKU: GGU8) is a fast-acting midget fuse designed for reliable overcurrent protection in industrial applications. Rated for 125VAC and 8 Amps, this fuse features standard midget dimensions of 1-1/2" x 13/32" (10 mm x 38 mm), ensuring compatibility with many existing fuse holders. Its 10kA interrupting rating provides robust protection for sensitive equipment. The GGU8 is specifically noted for its medium lag characteristic, suitable for circuits up to 30A and 125VAC. While fuses rated 20A and above in the GGU series utilize ceramic bodies for higher ambient temperature applications, the GGU8, like other ratings from 1A to 15A, features a glass body, allowing for clear visual inspection of the fusible element's status. This fuse is not intended for branch circuit protection. It is an ideal component for industrial power supplies, control equipment, automation systems, and specialized machinery where precise and dependable overcurrent protection is essential. Mersen is a recognized leader in electrical protection, and the GGU8 embodies their commitment to quality and performance. Professionals can rely on the GGU8 for consistent operation and safeguarding critical electrical systems. Compatible with Mersen's UltraSafe™ fuse holders (1-30A).
