Bussmann series FRS-R 600 V Class R up to 60 A fuse data sheet no. 1017
Feature: Time-delay, dual-element design with current-limiting protection. Benefit: Allows safe motor startup and surge handling while minimizing nuisance trips, reducing unplanned downtime in automation systems. Application: Ideal for motor drives, conveyors, and heavy-control panels where reliable inrush handling is critical. Feature: 7.5 A amperage rating with high interrupt capability (200 kAIC at 600 Vac; 20 kAIC at 300 Vdc). Benefit: Protects adjacent circuitry from high-energy faults, safeguarding equipment and lowering repair costs in high-demand environments. Application: Branch-circuit protection in industrial facilities and manufacturing lines. Feature: 600 Vac / 300 Vdc voltage rating with non-indicating ferrule-end connections. Benefit: Delivers robust performance across AC and DC sections while simplifying panel wiring and replacements in standard assemblies. Application: Control panels and feeder protection in mixed-voltage installations. Feature: Class RK5 construction and dual-element design. Benefit: Combines selective protection with rapid fault interruption, improving safety margins and compliance, while enabling easy integration with Bussmann series catalogs. Application: Electrical protection and circuit control in industrial settings. Feature: Compact form factor (5 in length, 0.81 in x 0.81 in) and ferrule-end termination. Benefit: Easier installation in tight panels and vertical mounting, with predictable footprint and straightforward replacement. Application: Retrofit projects and new builds requiring space-efficient protection.

FAQs
The FRS-R-7-1/2 uses ferrule-end connections, providing secure, reusable terminations suitable for standard Bussmann-series wiring practices. This ferrule-end design facilitates quick, reliable installation in control panels and bulkhead assemblies while maintaining consistent contact quality across replacements.
The fuse is rated at 7.5 A, with an interrupt rating of 200 kAIC at 600 Vac and 20 kAIC at 300 Vdc. It has a 600 Vac / 300 Vdc voltage rating and a response time of about 10 seconds at 500% overload, making it suitable for controlled startup and fault protection in mixed-voltage circuits.
The RK5 Class design combines time-delay operation with dual-element construction and current limiting to tolerate startup surges while quickly clearing faults. This reduces nuisance trips and protects sensitive components in industrial control panels, motor drives, and feeders, improving uptime and safety.
Yes, the FRS-R-7-1/2 is CE marked, indicating compliance with relevant European safety and performance standards. For additional regulatory information such as RoHS applicability, consult Eaton’s compliance resources or the RoHS search tool linked in Eaton’s documentation.
The fuse measures 5 inches in length with a 0.81 inch width and height, and it weighs about 0.159 lb. The ferrule-end terminations and standard packaging make it compatible with common control-panel layouts and provide a straightforward replacement process for existing RK5 FRS-R components.
