Littelfuse offers five different series of class RK5 fuses – the IDSR series, FLSR_ID series, FLNR_ID series, FLSR series and FLNR series.
The time-delay, dual-element IDSR series fuses combine a 600 V dc capability with indication to provide an ideal solution for many dc applications. These fuses offer a patented, state-of-the-art, solid-state design with maximum reliability and superior performance characteristics.
The FLSR_ID Indicator™ Series offers a patented, state-of-the-art, solid-state design with maximum reliability and superior performance characteristics. The dual-element design ensures advanced short-circuit and overload protection. This series offers visual blown fuse indication at a glance. The use of indicator fuses reduces downtime and nuisance opening, increases safety, and saves money by cutting down on lost production time. These fuses are also available in a...
Littelfuse FLNR_ID Indicator™ fuses provide visual blown fuse indication at a glance. The patented state-of-the-art solid state design provides maximum reliability and superior performance characteristics in a true dual-element design. The use of Indicator fuses reduces down-time, nuisance opening, increases safety, and can save thousands of dollars in lost production time.
The FLSR series dual-element, time-delay UL Class RK5 fuses are the most widely used fuse class. They offer superior performance and excellent protection for all types of circuits, especially those with motors. Precision manufactured parts ensure an accurate, consistent response to overloads and short-circuits. The FLSR fuses are also available in an indicating version, see the FLSR_ID series.
The FLNR series sets the standard for general purpose fuses. The dual-element design provides advanced short-circuit and overload protection. These time-delay fuses are also available in an indicating version, see FLNR_ID series.
