Frequently Asked Questions

What is the BUSSMANN FNA-25 fuse used for?

The BUSSMANN FNA-25 is a time-delay midget indicating fuse used for overcurrent protection in control circuits, lighting, and small transformer applications. Its time-delay characteristic allows it to withstand temporary inrush currents without nuisance opening, making it suitable for industrial equipment and panel boards.

What are the specifications of the BUSSMANN FNA-25 fuse?

The BUSSMANN FNA-25 is rated for 25 A at 32 V AC. It is part of the FNA Series, a time-delay midget indicating fuse with dimensions of 13/32 in x 1 1/2 in. The indicating feature provides visual identification of an open fuse, simplifying maintenance in industrial control panels.

Where to buy BUSSMANN FNA-25 fuses worldwide?

3G Electric supplies the BUSSMANN FNA-25 fuse worldwide. As a global industrial distributor, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time; we source and deliver this BUSSMANN fuse to support your maintenance or project needs.

How to select the correct BUSSMANN FNA-25 fuse for an application?

To select the BUSSMANN FNA-25, verify the circuit voltage does not exceed 32 V AC and the continuous current does not exceed 25 A. The time-delay feature is ideal for loads with inrush, such as motors or transformers. Ensure the fuse holder accommodates the 13/32 in x 1 1/2 in dimensions for proper fit.
