Bussmann series FRS-R 600 V Class R up to 60 A fuse data sheet no. 1017
Feature → Business Impact → Application: The time-delay, dual-element design provides tolerance for inrush currents common in control circuits, reducing nuisance trips while preserving protection for sensitive instrumentation. This translates to lower maintenance costs and higher production uptime in motor drives and logic panels, where precise current limiting matters. Application-tailored benefits include safer startup of automated equipment and improved reliability in fiber- or electronics-heavy environments. Feature → Business Impact → Application: The 0.01 A amperage rating delivers granular protection for low-current sensing and signal conditioning circuits, helping prevent nuisance shutdowns without exposing equipment to short-circuit damage in automation controllers. This is ideal for instrumentation racks, PLC power supplies, and distributed control systems that demand tight protection margins. Feature → Business Impact → Application: The 200 kAIC interrupt rating at 600 Vac and 20 kAIC at 300 Vdc provides rugged fault isolation, limiting downstream damage and accelerating recovery after a fault. This is crucial for panel boards and distributed power architectures in manufacturing lines where downtime directly impacts output. Feature → Business Impact → Application: The Class RK5 designation with ferrule end-to-end connections ensures compatibility with standard Bussmann RK5 holders, enabling fast, error-free installation and straightforward field replacement. This reduces commissioning time and lowers total cost of ownership for industrial automation projects. Feature → Business Impact → Application: Non-indicating status reduces panel clutter while delivering clear, maintenance-friendly protection in standard 5 inch long, ferrule-ended fuses. The compact 0.81 x 0.81 inch footprint and 0.15 lb weight fit neatly in crowded control cabinets, supporting compact layouts in modern machines. Feature → Business Impact → Application: CE marking and RoHS compatibility reassure compliance teams and procurement, supporting global deployments across factories and facilities that require regulatory alignment and sustainable components. This is especially valuable for multi-site rollouts and modernization initiatives in process automation and electrical protection systems.
