Overview

The Mersen GDG4/100 miniature time-delay fuse provides precise overcurrent protection for sensitive electronic and industrial systems. Rated at 250VAC and 0.04A, this 5x20mm ferrule fuse is designed to handle transient inrush currents common in motor startups, power supply activation, and other inductive loads. Its time-delay characteristic prevents nuisance tripping while ensuring protection against sustained overloads and short circuits. The glass body construction enables quick visual confirmation of fuse status, simplifying maintenance and troubleshooting. Typical applications include power supplies, consumer electronics, industrial control systems, instrumentation, telecommunications equipment, and medical devices where reliable fault protection is critical. The GDG4/100 offers a balance of sensitivity and transient tolerance, making it suitable for applications requiring both precision and durability.
