Overview

The Mersen GDG8/10 is a miniature time-delay fuse engineered for reliable circuit protection. It features a precise 0.8A current rating and operates at a maximum voltage of 250VAC. The fuse is constructed with a 5x20mm glass ferrule, a design that facilitates easy visual inspection of the fuse element and ensures secure, dependable mounting within standard fuse holders. This time-delay characteristic is crucial for applications where temporary overloads are expected, such as during motor startups or capacitor charging cycles. By tolerating these brief overcurrent events, the GDG8/10 effectively prevents nuisance tripping, thereby maintaining operational continuity. Its robust design makes it an ideal choice for a range of demanding applications, including industrial control panels, motor protection circuits, transformer protection, and power supply units. The GDG8/10 adheres to stringent international safety standards, specifically IEC 60127-2 and UL 248-14, guaranteeing consistent and dependable performance. The 5x20mm ferrule format is a widely adopted global standard, ensuring broad compatibility with a diverse array of fuse holders and electrical panels. Mersen's dedication to manufacturing excellence underpins the consistent performance of the GDG8/10, even in challenging industrial settings.
