Product Description

The MERSEN GSA Series is a time-delay cylindrical fuse, available as the GSA1/2 model (MPN GSA1/2). It is rated at 500 mA and 250 V AC, with a non-indicating design and dimensions of 1/4 in x 1 1/4 in. This fuse is equivalent to the MDA and GSA series.

Frequently Asked Questions

What is the MERSEN GSA Series fuse used for?

The MERSEN GSA Series time-delay cylindrical fuse is used for overcurrent protection in industrial equipment, motor circuits, and control panels. Its time-delay characteristic allows it to withstand temporary inrush currents without nuisance tripping, making it suitable for applications with inductive loads.

What are the specifications of the MERSEN GSA1/2 fuse?

The MERSEN GSA1/2 fuse is rated at 500 mA and 250 V AC, with a non-indicating design. It measures 1/4 in x 1 1/4 in and belongs to the GSA Series, which is equivalent to the MDA and GSA series. The manufacturer part number is GSA1/2.

Where to buy MERSEN GSA Series fuses worldwide?

You can source MERSEN GSA Series 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 time on the GSA1/2 model.

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

To select the correct MERSEN GSA fuse, verify the voltage rating (250 V AC), current rating (500 mA for GSA1/2), and physical dimensions (1/4 in x 1 1/4 in). Ensure the time-delay characteristic matches your circuit's inrush requirements. Consult the equipment manual or a qualified engineer for proper coordination.
