Frequently Asked Questions

What is the MERSEN GSF Series fuse used for?

The MERSEN GSF Series time-delay fuse protects circuits against overcurrents while tolerating temporary inrush currents, common in industrial control panels, power supplies, and motor starter circuits. Its 5 mm x 20 mm package fits standard fuse holders across electrical distribution and machinery applications.

What are the specifications of the MERSEN GSF6-3/10 fuse?

The MERSEN GSF6-3/10 is a 6.3 A, 250 V AC time-delay cylindrical fuse with a non-indicating design. It measures 5 mm x 20 mm and is equivalent to the S505, 477, and GSF series. The manufacturer part number is GSF6-3/10.

Where to buy MERSEN GSF series fuses worldwide?

3G Electric supplies MERSEN GSF series fuses worldwide, handling full logistics and customs clearance for international orders. As a global industrial sourcing partner, we provide genuine MERSEN fuses like the GSF6-3/10 to customers across 14 industrial departments, including electrical and power transmission.

How to select the correct MERSEN GSF fuse for a circuit?

Select a MERSEN GSF fuse by matching the voltage rating (250 V AC) and current rating (6.3 A) to your circuit requirements. The time-delay characteristic allows brief overloads, so verify the inrush current duration of your load. Always consult the equipment manual or a qualified engineer for proper coordination.
