Product Description

The MERSEN GDL Series Time-Delay Cylindrical Fuse (MPN GDL1/2) is a 500 mA, 250 V AC fuse with a 1/4 in x 1 1/4 in body size. This time-delay fuse is designed for applications requiring protection against temporary inrush currents without nuisance opening.

Frequently Asked Questions

What is the MERSEN GDL Series fuse used for?

The MERSEN GDL Series time-delay cylindrical fuse is used to protect electrical circuits from overcurrent while tolerating temporary inrush currents, preventing nuisance opening. It is commonly applied in industrial control panels, power supplies, and motor circuits where brief current surges occur during startup.

What are the specifications of the MERSEN GDL1/2 fuse?

The MERSEN GDL1/2 fuse is rated at 500 mA and 250 V AC. It features a time-delay characteristic and a cylindrical body size of 1/4 in x 1 1/4 in. This fuse is part of the GDL series and is designed to handle inrush currents without premature blowing.

Where to buy MERSEN GDL1/2 fuses worldwide?

You can source MERSEN GDL1/2 fuses through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we supply genuine MERSEN components for industrial applications.

How to select the correct MERSEN GDL fuse for an application?

To select the correct MERSEN GDL fuse, match the voltage rating (250 V AC) and current rating (e.g., 500 mA for GDL1/2) to your circuit requirements. Ensure the time-delay characteristic suits your inrush current profile. Verify the physical size (1/4 in x 1 1/4 in) fits your fuse holder. Consult MERSEN documentation for coordination studies.
