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.
