Frequently Asked Questions

What is the MERSEN GSA Series fuse used for?

The MERSEN GSA Series time-delay fuse is used for overcurrent protection in industrial equipment, motor circuits, and control panels where a temporary inrush current is expected. Its 1.25 A rating and 250 V AC capacity make it suitable for sensitive electronics and machinery requiring reliable, non-indicating protection.

What are the specifications of the MERSEN GSA1-1/4 fuse?

The MERSEN GSA1-1/4 is a time-delay cylindrical fuse rated at 1.25 A and 250 V AC. It has a non-indicating design, dimensions of 1/4 in x 1 1/4 in, and is part of the GSA series, equivalent to the MDA and GSA fuse series. The manufacturer part number is GSA1-1/4.

Where to buy MERSEN GSA1-1/4 fuses worldwide?

You can source MERSEN GSA1-1/4 fuses worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead times on this MERSEN fuse.

How to select the right MERSEN GSA fuse for my application?
