FAQs
The BK/FRN-R-1-6/10 is designed for motor protection and control circuits in industrial panels. It operates at 250 Vac and 125 Vdc, aligns with RK5 class standards, and is suitable for machine panels and drive systems where reliable inrush handling and fast fault interruption are required. Use with RK5-compatible holders and standard bulk intake processes for efficient stocking.
This fuse features a 1.6 A amperage rating, a dual-element time-delay design, and a 200 kAIC interrupt rating at both 250 Vac and 125 Vdc. It has a response time of 8 seconds at 500% overload, and a voltage rating of 250 Vac / 125 Vdc, making it suitable for mixed AC and DC control circuits in industrial equipment.
Yes. The FRN-R fuse is specifically intended for motor overload and short-circuit protection in panels. Its current-limiting, time-delay characteristics allow motor inrush during startup while protecting against sustained faults, helping to maintain uptime and reduce wear on drives, contactors, and wiring.
The BK/FRN-R-1-6/10 is CE Marked and classed as RK5, ensuring European compliance and standardization in motor-protection applications. The high interrupt rating supports rigorous fault scenarios, and the bulk packaging simplifies procurement and stocking practices for maintenance and OEM programs.
Match the fuse to the motor load and inrush profile; pair with appropriate soft-start or VFD controls when applicable; ensure correct RK5 fuse type to prevent mis-selection. Using the 1.6 A rating for small motors and confirming the circuit voltage (250 Vac / 125 Vdc) helps prevent nuisance trips and downtime during startup.
