Bussmann series FRS-R 600 V Class R up to 60 A fuse data sheet no. 1017
Time-delay, dual-element, current-limiting RK5 fuse provides selective protection that tolerates short overloads without unnecessary trips. This reduces nuisance tripping and downtime on motor starters and control circuits, while still clearing faults quickly to protect equipment. Application: ideal for pump, conveyor, and fan drives in manufacturing and packaging lines. 1 A amperage rating and precise current protection prevent damage to small control circuits and PLC power rails, extending module life and reducing spare parts. Application: control panels, instrumentation racks, and small-distribution feeders. High interrupt ratings—200 kAIC at 600 Vac and 20 kAIC at 300 Vdc—ensure fault currents are interrupted safely, reducing arcing risk and downstream damage in high-energy systems. Application: main feeders and cabinet boards in industrial facilities. Ferrule end x ferrule end terminals and a 5 in length with 0.81 in width/height enable easy drop-in replacement in standard Bussmann holders and enclosures. Application: retrofit projects or new builds in control enclosures. Non-indicating fuse with CE marking and RoHS compliance reduces visual wear in panel dashboards while meeting regulatory requirements and environmental standards. Application: general purpose protection in compliant electrical assemblies.

FAQs
Install the FRS-R-1 in compatible RK5 fuse holders with ferrule-end terminals; its 5 inch length and 0.81 inch square profile fit standard control panels. Use standard Bussmann-series holders and observe enclosure clearance. The device is CE marked and RoHS compliant, aiding regulatory documentation and audits.
The time-delay feature tolerates brief overloads during motor startup without tripping, while the dual-element construction provides fast fault interruption for sustained faults. This reduces nuisance trips, protects equipment, and supports continuous operation of pumps, conveyors, and fans in production lines.
Yes. With a 600 Vac and 300 Vdc rating and a 200 kAIC at 600 Vac (20 kAIC at 300 Vdc), the FRS-R-1 is well-suited for high-energy feeders and branch circuits in industrial facilities, as well as control-panel power rails and distribution boards.
The FRS-R-1 is CE marked and RoHS compliant, aligning with key international safety and environmental standards. It belongs to the RK5 family, offering recognized classification for branch-circuit fuses in industrial applications and compliant installation in regulated environments.
The time-delay and current-limiting features reduce nuisance trips and downtime, improving equipment uptime and production throughput. Its robust interrupt ratings minimize downstream damage, lowering repair costs, while easy integration with standard Bussmann holders simplifies stocking and maintenance planning.
