Product Description

The BUSSMANN FRS-R-45ID is a Class RK5, time-delay cylindrical fuse from the FRS-R-ID Series, rated at 45 A, 600 V AC and 250 V DC, with an indicating feature. This fuse is designed for overcurrent protection in industrial electrical systems, offering time-delay characteristics to accommodate inrush currents.

Frequently Asked Questions

What is the BUSSMANN FRS-R-45ID fuse used for?

The BUSSMANN FRS-R-45ID is a Class RK5 time-delay indicating fuse rated 45 A, 600 V AC, and 250 V DC. It protects motor circuits, transformers, and other inductive loads where temporary inrush currents occur. The indicating feature provides a visual signal when the fuse has opened, simplifying troubleshooting in industrial control panels and distribution equipment.

What are the specifications of the BUSSMANN FRS-R-45ID fuse?

The BUSSMANN FRS-R-45ID is a Class RK5 time-delay cylindrical fuse rated 45 A, 600 V AC, and 250 V DC. It belongs to the FRS-R-ID series and features an indicating function that shows when the fuse has blown. The manufacturer part number is FRS-R-45ID. This fuse is designed for overcurrent protection in industrial applications.

Where to buy BUSSMANN FRS-R-45ID fuses worldwide?

BUSSMANN FRS-R-45ID fuses are available to order through 3G Electric, a global industrial equipment distributor. We source and deliver this fuse worldwide, handling full logistics and customs clearance. Contact 3G Electric for availability and lead time. We supply genuine BUSSMANN components to industrial customers across multiple regions.

How to select the correct BUSSMANN FRS-R-ID series fuse?

To select the correct BUSSMANN FRS-R-ID series fuse, match the voltage rating (600 V AC or 250 V DC) and current rating (45 A for the FRS-R-45ID) to your circuit requirements. The time-delay characteristic handles motor start-up surges. The indicating feature aids visual inspection. Always verify the Class RK5 rejection feature prevents substitution with lower-rated fuses.
