Frequently Asked Questions

What is the BUSSMANN FNM-20 fuse used for?

The BUSSMANN FNM-20 is a time-delay cylindrical fuse used to protect electrical circuits from overloads and short circuits. It is commonly applied in industrial control panels, motor circuits, and lighting systems where temporary inrush currents occur, allowing the fuse to pass without nuisance opening.

What are the specifications of the BUSSMANN FNM-20 fuse?

The BUSSMANN FNM-20 is a Midget time-delay fuse rated at 20 A and 250 V AC. It has a non-indicating design with dimensions of 13/32 in x 1 1/2 in. The manufacturer part number is FNM-20, and it belongs to the FNM Series from BUSSMANN.

Where to buy the BUSSMANN FNM-20 fuse worldwide?

You can source the BUSSMANN FNM-20 fuse 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 time; we supply genuine BUSSMANN components to industrial buyers globally.

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

To select the correct BUSSMANN FNM series fuse, match the voltage rating (250 V AC) and current rating (e.g., 20 A) to your circuit requirements. Consider the time-delay characteristic for motor or transformer loads with inrush. Verify physical dimensions (13/32 in x 1 1/2 in) fit your fuse holder. Consult a qualified engineer for coordination studies.
