Bussmann series Fusetron FRN-R RK5 fuse data sheet for fuses 70 to 600 amps No. 1020
Time-delay, dual-element design provides surge tolerance and selective protection, reducing nuisance trips while safeguarding downstream equipment. This translates to improved uptime and fewer unplanned shutdowns in automated lines; ideal for motor starts and equipment with brief inrush currents. The 110 A amperage rating with a 250 Vac and 125 Vdc operating range offers versatile protection across control circuits and small drives, enabling standardized use across multiple machines. Its 2 inch blade-end construction simplifies retrofits and panel upgrades, supporting fast, tool-free replacements in crowded enclosures while maintaining a clean, fault-tolerant protection scheme. The Class RK5, CE marking, and RoHS compliance help ensure regulatory alignment, procurement consistency, and reduced compliance costs across international projects. For data sheets and compatibility, refer to the Bussmann RK5 FRN-R RK5 fuse data sheet No. 1020.

FAQs
The FRN-R-110 uses blade end x blade end connections and has a 2 inch length, making it a drop-in fit for RK5 fuse holders and standard panels. Ensure proper cooling, verify panel clearance, and match the fuse holder to the RK5 family. Use the FRN-R-110 in circuits that require 110 A protection with dual-element time-delay for motor starts and transient loads.
Key ratings include 110 A amperage, 250 Vac and 125 Vdc voltage ratings, and an interrupt rating of 200 kAIC at 250 Vac and 20 kAIC at 125 Vdc. It is a time-delay, dual-element, current-limiting fuse designed to tolerate short surges during startup without compromising circuit protection, improving reliability in automated equipment.
Best suited for industrial automation, control panels, motor control centers, and power distribution in manufacturing environments. The RK5 class fuse provides reliable protection for circuits with startup inrush, allowing selective coordination with other fuses while maintaining compact panel footprints.
The FRN-R-110 is CE marked and RoHS compliant, aligning with European regulatory requirements. As part of the Class RK5 family, it follows Bussmann series standards for reliability and compatibility with other RK5 devices, facilitating compliant procurement and standardized panel protection.
By tolerating startup surges and transient overloads, the FRN-R-110 reduces nuisance trips, minimizing unplanned downtime and maintenance visits. Its compact form factor and straightforward replacement process shorten service windows, while reliable protection lowers downstream equipment damage risk, delivering a lower total cost of ownership over the panel’s lifecycle.
