Product Description

The MERSEN GSA Series is a time-delay cylindrical fuse rated at 5 A and 250 V AC, with a non-indicating design and dimensions of 1/4 in x 1 1/4 in. It is equivalent to the MDA and GSA fuse series, identified by manufacturer part number GSA5.

Frequently Asked Questions

What is the MERSEN GSA5 fuse used for?

The MERSEN GSA5 is a 5 A, 250 V AC time-delay cylindrical fuse used for overcurrent protection in industrial control panels, motor circuits, and lighting systems. Its time-delay characteristic allows it to withstand temporary inrush currents without nuisance opening, making it suitable for applications with inductive loads.

What are the specifications of the MERSEN GSA5 fuse?

The MERSEN GSA5 is a 5 A, 250 V AC time-delay fuse from the GSA series. It has a non-indicating design and measures 1/4 in x 1 1/4 in. It is equivalent to the MDA and GSA fuse series, with manufacturer part number GSA5. This fuse is suitable for branch circuit protection in industrial equipment.

Where to buy MERSEN GSA5 fuses worldwide?

You can source MERSEN GSA5 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 times. 3G Electric supplies genuine MERSEN components for industrial applications.

How to select the correct MERSEN GSA5 fuse for an application?

To select the correct MERSEN GSA5 fuse, verify the circuit voltage does not exceed 250 V AC and the continuous current does not exceed 5 A. Ensure the time-delay characteristic matches your load's inrush profile. The 1/4 in x 1 1/4 in dimensions fit standard fuse holders. Always consult the equipment manual for fuse requirements.
