Product Description

The BUSSMANN FRS-R Series Class RK5 Time-Delay Cylindrical Fuse (MPN FRS-R-2-1/4) is a non-indicating, 2.25 A fuse rated for 600 V AC and 300 V DC.

Frequently Asked Questions

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

The BUSSMANN FRS-R-2-1/4 is a Class RK5 time-delay cylindrical fuse rated 2.25 A, 600 V AC / 300 V DC. It protects motor circuits, transformers, and other inductive loads from overcurrent while tolerating harmless inrush currents. Common in industrial control panels and HVAC equipment.

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

This BUSSMANN FRS-R Series fuse has a current rating of 2.25 A, voltage rating of 600 V AC and 300 V DC, and is non-indicating. It is a Class RK5 time-delay cylindrical fuse with MPN FRS-R-2-1/4. The time-delay feature handles temporary overloads without nuisance opening.

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

3G Electric supplies BUSSMANN FRS-R-2-1/4 fuses worldwide. As a global industrial distributor since 1990, we handle full logistics, customs clearance, and delivery to any destination. Contact us for availability and lead time. We source and deliver genuine BUSSMANN components globally.

How to select the correct BUSSMANN FRS-R fuse for an application?

To select the correct BUSSMANN FRS-R fuse, match the voltage rating (600 V AC / 300 V DC) and current rating (2.25 A) to your circuit requirements. Ensure the Class RK5 rejection base matches your fuse holder. For motor protection, verify the time-delay characteristic accommodates starting inrush current without nuisance tripping.
