Overview

The Mersen GDG5/100 is a miniature time-delay fuse designed for reliable overcurrent protection in compact electrical systems. This 5x20mm glass ferrule fuse operates at 250VAC and has a 0.05A current rating. Its time-delay (slow-blow) characteristic is crucial for applications with transient overloads or inrush currents, such as motor startups or capacitive loads, preventing nuisance tripping. The GDG5/100 is suitable for sensitive electronic circuits, control panels, and instrumentation. Typical applications include industrial automation, telecommunications, power supplies, and medical devices. Mersen is a recognized leader in electrical protection, ensuring consistent performance and compliance with international safety standards like IEC 60127. The fuse's glass body allows for visual inspection, and its ferrule terminals ensure secure electrical contact. When selecting, consider the maximum continuous current, voltage rating, and interrupting capacity of your application. The GDG5/100 offers long-term reliability and cost efficiency by reducing equipment damage and downtime.
