Littelfuse FLSR ID Fuses Provide Exceptional Overcurrent Protection with Indication
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 non-indicating version, see FLSR series.
