Product Description

The BUSSMANN FNA Series is a time-delay cylindrical fuse, specifically a midget fuse rated at 2.5 A and 250 V AC. It features an indicating function and has dimensions of 13/32 in x 1 1/2 in, with the manufacturer part number FNA-2-1/2.

Frequently Asked Questions

What is the BUSSMANN FNA-2-1/2 fuse used for?

The BUSSMANN FNA-2-1/2 is a time-delay midget fuse rated 2.5 A and 250 V AC. It protects industrial control circuits, motor starters, and solenoid valves from overcurrent while tolerating harmless inrush currents. Its indicating feature allows quick visual identification of a blown fuse, reducing downtime in plant maintenance.

What are the specifications of the BUSSMANN FNA-2-1/2 fuse?

The BUSSMANN FNA-2-1/2 is a 2.5 A, 250 V AC time-delay midget fuse from the FNA Series. It has a 13/32 in x 1 1/2 in cylindrical body with an indicating function. The manufacturer part number is FNA-2-1/2. It is designed for overcurrent protection in industrial equipment where time-delay characteristics are required.

Where to buy the BUSSMANN FNA-2-1/2 fuse worldwide?

3G Electric supplies the BUSSMANN FNA-2-1/2 fuse to customers worldwide. As a global industrial solutions provider, we handle full logistics, customs clearance, and delivery to your facility. Contact us for a quote and lead time on this and other BUSSMANN FNA Series fuses.

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

To select the correct BUSSMANN FNA series fuse, match the voltage rating (250 V AC) and current rating (2.5 A) to your circuit requirements. The time-delay characteristic is ideal for loads with high inrush current, such as motors and transformers. Verify the physical dimensions (13/32 in x 1 1/2 in) fit your fuse holder. 3G Electric can help confirm the right part.
