FAQs
Ensure ferrule-end terminations are properly crimped and seated in the panel bus connections. The FRN-R-15 is a 2 in long, 0.56 in square device designed for standard RK5 enclosures; verify clearance, wiring depth, and compatible fuse blocks to maintain correct coordination with upstream protection.
The FRN-R-15 is rated for 15 A with a voltage rating of 250 Vac and 125 Vdc, offering an interrupt rating of 200 kAIC at 250 Vac and 20 kAIC at 125 Vdc, and a time-delay, dual-element design for inrush tolerance.
Yes. FRN-R-15 is part of the Bussmann RK5 family and shares the same mounting and coordination characteristics, enabling consistent protection across RK5 devices in a control panel or branch circuit.
Ideal for control panels, motor control centers, and branch circuits requiring reliable, time-delay protection with current limiting to minimize nuisance trips during startup while maintaining safety and coordination with higher-capacity feeders.
FRN-R-15 carries CE Marking for European compliance. While other certifications aren’t listed in the data, the device is designed to conform with RK5 class protection standards and relevant safety practices for industrial electrical protection.
