Frequently Asked Questions

What is the MERSEN GDG4 fuse used for?

The MERSEN GDG4 is a time-delay cylindrical fuse used for overcurrent protection in industrial equipment. Its 4 A, 250 V AC rating and 5.1 mm x 20.1 mm size make it suitable for protecting control circuits, power supplies, and machinery from short circuits and overloads.

What are the specifications of the MERSEN GDG4 fuse?

The MERSEN GDG4 is a time-delay cylindrical fuse rated at 4 A and 250 V AC, with dimensions of 5.1 mm x 20.1 mm. It belongs to the GDG series and is designed for overcurrent protection in industrial applications. The manufacturer part number is GDG4.

Where to buy MERSEN GDG4 fuses worldwide?

3G Electric supplies MERSEN GDG4 fuses worldwide. As a global industrial solutions provider, we handle full logistics, customs clearance, and delivery to your location. Contact us to source this time-delay fuse for your overcurrent protection needs.

How to select the right MERSEN GDG series fuse?

To select the right MERSEN GDG series fuse, match the voltage rating (250 V AC) and current rating (4 A for GDG4) to your circuit requirements. Ensure the physical dimensions (5.1 mm x 20.1 mm) fit your fuse holder. Time-delay fuses tolerate temporary inrush currents, ideal for inductive loads.
