Bussmann series Fusetron FRN-R RK5 fuse data sheet for up to 60 amps No. 1019
The FRN-R is a time-delay, dual-element current-limiting fuse from Eaton Bussmann RK5 designed for branch circuits in industrial control panels. This combination enables reliable fault clearing while minimizing nuisance trips, helping automation equipment like motor starters and PLC-controlled feeders stay online. With a 200 kAIC interrupt rating at 250 Vac and 20 kAIC at 125 Vdc, it tolerates high fault currents without compromising downstream devices. That energy-absorption protects cables, relays, and contactors in demanding environments, improving equipment life and reducing replacement costs. Physically, the FRN-R-30ID measures 2 inches in length with a compact 0.56 inch width and height and weighs about 0.5 pounds, enabling tight panel fits. Ferrule-end connections simplify secure terminations and support quick field installation across standard control panels. The fuse delivers an 8-second response at 500% overload, providing predictable protection timing for transient faults. Finger-safe construction and a power loss of 5.45 W enhance operator safety and reduce heat generation in enclosed enclosures. Indicator variants allow fast fault diagnostics, while non-indicating options keep protection lean for silent operation. CE marking and Class RK5 designation ensure compliance with European safety requirements and enable straightforward integration into global projects. Compatibility with ferrule-end terminations and standard cataloging streamlines BOMs and reduces spare-parts variety across plants. Overall, FRN-R-30ID delivers consistent protection, lowers maintenance costs, and helps meet uptime targets in industrial automation environments. For field service, confirm the FRN-R-30ID is used within its 250 Vac /125 Vdc range and that ferrule-end terminations are correctly crimped. During installation, maintain clean, dry terminals and follow standard torque specs to preserve interruption performance. If your maintenance workflow relies on diagnostics, select the indicating variant to provide visible fault signaling without invasive inspection. Linking these fuses to a common RK5 BOM reduces SKU proliferation, lowers stocking costs, and improves mean time to repair in manufacturing environments across multiple lines.

FAQs
FRN-R-30ID uses ferrule-end terminations on both ends, simplifying secure field wiring. Use standard ferrule crimps sized for the fuse diameter and ensure clean, straight crimps; avoid copper strands under the ferrule. The compact 2 in length and ferrule-end-to-end configuration support reliable mounting in crowded panels and improve installer ergonomics. Also inspect indicators if using the indicator variant to validate status at a glance.
Key electrical ratings include a 30 A current rating, 200 kAIC interrupt rating at 250 Vac, and 20 kAIC at 125 Vdc. The device supports voltage ratings of 250 Vac and 125 Vdc and is designed for rapid fault clearing while meeting industry requirements. The 8-second response time at 500% overload provides predictable protection during surge events.
RK5 Class means this FRN-R-30ID is a Class RK5, time-delay, dual-element fuse designed for current-limiting protection in branch circuits. It delivers controlled response to overloads while tolerating short surges, enabling selective coordination with downstream devices. This alignment with RK5 standards simplifies integration into existing Eaton Bussmann catalogs and supports consistent protection across panels.
Yes. The FRN-R-30ID is suited for motor control circuits and general power distribution in industrial panels, with a 30 A rating and dual-element design that improves selectivity and fault clearance. It supports reliable protection for feeders, relays, and contactors, while its compact form factor eases retrofits in crowded enclosures today.
From a maintenance and ROI perspective, the FRN-R-30ID offers safer field servicing with finger-safe construction and a predictable 8-second response at overload, reducing downtime during faults. Standard RK5 compatibility and end-to-end ferrule terminals simplify parts management, lowering spare-parts variety and enabling faster replacement in high-volume manufacturing environments across multiple lines.
