Bussmann series FRS-R 600 V Class R up to 60 A fuse data sheet no. 1017
Time-delay, dual-element design delivers selective protection while tolerating brief inrush currents. This reduces nuisance trips and helps extend motor life and equipment uptime in demanding environments such as manufacturing lines and packaging facilities. The result is smoother startup behavior and a lower total cost of ownership for electrical protection in panels, MCCs, and feeder circuits. High interrupt rating up to 200 kAIC at 600 Vac and 20 kAIC at 300 Vdc ensures robust fault handling for heavy loads, minimizing collateral damage and downtime in critical production lines. Class RK5 fuse technology enables precise selective coordination, improving system reliability and simplifying panel design in distributed control architectures. Ferrule-end connections enable quick, secure installation and straightforward retrofits in existing Bussmann series fixtures. Non-indicating design reduces wiring complexity and maintenance overhead, while preserving clear fault isolation during inspections. Overall, this fuse supports compliant, efficient, and scalable protection across industrial automation and electrical protection applications.

FAQs
The FRS-R-5-6/10 uses ferrule-end connections and is designed for Class RK5 fuse holders compatible with Bussmann series equipment. Its 5 inch body length and 0.81 inch width fit standard low-voltage fuse blocks, enabling easy replacement in control panels and MCCs without requiring special adapters. This reduces downtime during maintenance events and supports straightforward retrofit projects in industrial automation systems.
Key specs to review are the amperage rating of 5.60A, the time-delay characteristic, and the interrupt ratings of 200 kAIC at 600 Vac and 20 kAIC at 300 Vdc. The 10 second response at 500% helps accommodate brief inrush without nuisance trips, making the FRS-R-5-6/10 suitable for motors and drives in manufacturing environments where load surges are common.
Yes. The dual-element time-delay design is specifically intended for motor protection and other inductive loads. Its Class RK5 classification supports selective coordination, helping to prevent simultaneous tripping across downstream devices. When used in motor control centers and control panels, it provides reliable protection against short circuits while minimizing downtime during normal operation.
The fuse is CE marked, indicating compliance with European safety standards. While the primary data cites CE marking, RoHS compliance can be verified via Eaton’s RoHS tool referenced in the downloads. For European installations, confirm RoHS status during procurement and ensure all ancillary components meet local environmental and safety regulations.
The FRS-R-5-6/10 delivers lower nuisance trips and robust fault handling, which translates to reduced unplanned downtime and shorter repair windows. Its non-indicating design minimizes on-panel maintenance, while the ferrule-end connections simplify replacement. Over time, this can lower total maintenance costs and improve facility uptime, especially in high-demand environments like automated production lines and packaging facilities.
