Frequently Asked Questions

What is the BUSSMANN FRS-R-7-1/2ID fuse used for?

The BUSSMANN FRS-R-7-1/2ID is a Class RK5, time-delay, indicating fuse rated 7.5 A, 600 V AC, 300 V DC. It protects motor circuits, transformers, and other inductive loads where temporary inrush currents occur. The indicating feature provides visual identification of a blown fuse, speeding troubleshooting in industrial control panels and distribution equipment.

What are the specifications of the BUSSMANN FRS-R-7-1/2ID fuse?

The BUSSMANN FRS-R-7-1/2ID is a Class RK5, time-delay, indicating fuse from the FRS-R-ID series. It is rated 7.5 A, 600 V AC, 300 V DC. The cylindrical body is designed for rejection-style fuse holders. The manufacturer part number is FRS-R-7-1/2ID. It provides overload and short-circuit protection with a visible blown-fuse indicator.

Where to buy the BUSSMANN FRS-R-7-1/2ID fuse worldwide?

3G Electric supplies the BUSSMANN FRS-R-7-1/2ID fuse to customers worldwide. As a global industrial equipment distributor established in 1990, we handle full logistics, customs clearance, and delivery to your location. Contact 3G Electric for pricing and lead time on this Class RK5, time-delay, indicating fuse.

How to select the correct BUSSMANN FRS-R-ID series fuse for a motor circuit?

Select the BUSSMANN FRS-R-ID series fuse based on the motor's full-load current and starting characteristics. For a 7.5 A rating like the FRS-R-7-1/2ID, ensure the continuous load does not exceed 7.5 A and that the time-delay feature accommodates motor inrush. Always verify voltage ratings (600 V AC / 300 V DC) and use rejection-style holders for Class RK5 fuses.
