Product Description

The BUSSMANN FNQ Series is a time-delay cylindrical fuse, specifically a midget fuse rated at 4.5 A and 500 V AC. It has dimensions of 13/32 in x 1 1/2 in and is non-indicating, with the manufacturer part number FNQ-4-1/2.

Frequently Asked Questions

What is the BUSSMANN FNQ-4-1/2 fuse used for?

The BUSSMANN FNQ-4-1/2 is a time-delay midget fuse used for overcurrent protection in industrial control circuits, motor starters, and lighting systems. Its 4.5 A rating and 500 V AC capacity make it suitable for branch circuits where temporary inrush currents occur, preventing nuisance blowing.

What are the specifications of the BUSSMANN FNQ-4-1/2 fuse?

The BUSSMANN FNQ-4-1/2 is a 4.5 A, 500 V AC time-delay midget fuse from the FNQ series. It measures 13/32 in x 1 1/2 in, is non-indicating, and has the manufacturer part number FNQ-4-1/2. It is designed for cylindrical fuse holders and provides reliable overcurrent protection.

Where to buy BUSSMANN FNQ-4-1/2 fuses worldwide?

You can source BUSSMANN FNQ-4-1/2 fuses through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations.
