FLNR003 - 3 Amp Fuse
The FLNR003 is a 3 Amp Class RK5 fuse designed for electrical applications that require a dual-element, time-delay fuse for dependable overcurrent protection. When you're replacing a fuse in an existing electrical system, choosing the correct fuse class, amp rating, and voltage rating is important to maintaining the original protection setup. The FLNR003 is commonly used in industrial and commercial equipment where circuits may experience temporary startup currents but still need protection from sustained overload conditions.
