Product Description

The MERSEN GDG Series is a time-delay cylindrical fuse rated at 125 mA and 250 V AC, with dimensions of 5.1 mm x 20.1 mm. This MERSEN fuse, model GDG1/8, provides overcurrent protection in a compact glass tube design.

Frequently Asked Questions

What is the MERSEN GDG Series fuse used for?

The MERSEN GDG Series time-delay fuse (125 mA, 250 V AC) protects sensitive equipment from overcurrent in industrial control panels, instrumentation, and power supplies. Its compact 5.1 mm x 20.1 mm glass tube design fits standard fuse holders, and the time-delay characteristic handles inrush currents without nuisance tripping.

What are the specifications of the MERSEN GDG1/8 fuse?

The MERSEN GDG1/8 is a time-delay cylindrical fuse rated at 125 mA and 250 V AC. It measures 5.1 mm x 20.1 mm and belongs to the GDG Series. The glass tube construction provides reliable overcurrent protection in a compact form factor suitable for industrial and commercial applications.

Where to buy MERSEN GDG Series fuses worldwide?

3G Electric supplies MERSEN GDG Series fuses (including GDG1/8) to customers worldwide. As a global industrial sourcing partner, we handle logistics, customs clearance, and delivery to your location. Contact us for pricing and lead time on this time-delay fuse.

How to select the correct MERSEN GDG fuse for my application?

To select the right MERSEN GDG fuse, match the voltage rating (250 V AC) and current rating (125 mA for GDG1/8) to your circuit requirements. The time-delay characteristic is ideal for loads with startup surges. Always verify the physical dimensions (5.1 mm x 20.1 mm) fit your fuse holder.
