FAQs
Install FRN-R-1-1/8 by aligning the dual-element fuse with the holder contacts, ensuring the 3 in length sits securely in the mounting slot. The nickel-plated endcaps provide reliable contact load and corrosion resistance, while the non-indicating design simplifies replacement workflows during routine maintenance or field service. Verify voltage rating (250 Vac or 125 Vdc) aligns with your panel circuitry and observe proper clearance for arcing distance.
Key specs include a 1.125 A amperage rating, 200 kAIC interrupting rating at 250 Vac, and 20 kAIC at 125 Vdc. It is time-delay (8 sec at 500%), dual-element, current-limiting, with a 3 inch length and 0.81 inch width/height, weighing 0.8 lb. The fuse is CE marked and designed for Bussmann RK5 branch-circuit protection in industrial controls.
Yes. Its time-delay and dual-element design handle inrush currents typical of motor starters, while the current-limiting feature helps limit fault energy. With a 1.125 A rating, it suits low-current control circuits and auxiliary power feeds in automation panels, providing safe coordination with upstream protective devices and minimizing nuisance trips during normal startup sequences.
The FRN-R-1-1/8 is CE marked, confirming European regulatory alignment for electrical protection devices. While the data highlights this CE compliance, always verify site-specific standards and any additional regional requirements (UL/CSA or IP ratings) with your procurement team, as these depend on the end-application and enclosure environment.
Expect ROI from reduced downtime due to fewer nuisance trips, lower fault-energy damage because of current-limiting action, and streamlined maintenance thanks to a non-indicating fuse in a compact form factor. The fuse’s 3 in length and durable nickel-plated endcaps also support quicker replacements and longer service life in demanding industrial environments.
