Frequently Asked Questions

What is the BUSSMANN FRN-R-225 fuse used for?

The BUSSMANN FRN-R-225 is a Class RK5 time-delay fuse rated 225 A at 250 V AC/DC. It protects motors, transformers, and other inductive loads from short circuits and sustained overloads. Its time-delay characteristic prevents nuisance opening during inrush currents, making it suitable for industrial power distribution and control panels.

What are the specifications of the BUSSMANN FRN-R-225 fuse?

The BUSSMANN FRN-R-225 is a Class RK5, time-delay, non-indicating fuse rated 225 A at 250 V AC and 250 V DC. It belongs to the FRN-R series and is designed for branch-circuit protection. The fuse provides high interrupting capacity and meets UL/CSA requirements for industrial applications.

Where to buy the BUSSMANN FRN-R-225 fuse worldwide?

How to select the correct BUSSMANN FRN-R-225 fuse for an application?

To select the BUSSMANN FRN-R-225, verify the system voltage does not exceed 250 V AC or DC and the continuous load current is below 225 A. Ensure the fuse class (RK5) matches the panel's interrupting rating. For motor circuits, confirm the time-delay characteristic accommodates starting inrush. Consult a licensed electrician for code compliance.
