FAQs
FRN-R-600 uses blade-end connections, a common RK5 fuse form factor compatible with Bussmann RK5 holders and standard control panels. It installs like-for-like in panels designed for 600 A class RK5 fuses, reducing retrofit complexity. Verify blade spacing and mounting clearance in your enclosure to ensure a secure, compliant fit during maintenance or replacement.
FRN-R-600 provides an interrupt rating of 200 kAIC at 250 Vac and 20 kAIC at 125 Vdc. This high fault-current capability allows safe disconnection of large short-circuit currents, protecting downstream components like contactors, transformers, and wiring insulation. Use this rating to design for reliable protection in high-energy power distribution and motor-control environments.
Yes. The FRN-R-600 is a time-delay, dual-element fuse designed to tolerate motor inrush while still limiting fault current. This reduces nuisance tripping on startup and preserves motor windings, drives, and control electronics. It's well-suited for motor starters, drives, and CNC machinery where controlled inrush is expected.
The FRN-R-600 is CE Marked, aligning with European safety requirements and enabling use in global electrical panels. It is part of the Eaton Bussmann RK5 family, offering a documented, standards-aligned protection solution for panelboards, motor control centers, and power distribution blocks across diverse markets.
The FRN-R-600 improves uptime by reducing nuisance trips through time-delay operation, while its high interrupt rating minimizes downstream damage in fault events. Combined with standardized RK5 compatibility and documented performance, these factors lower maintenance costs, shorten downtime, and simplify spare-part inventories for large-scale automation projects.
