Littelfuse FLSR.100 Industrial Cartridge Fuse 0.1A Slo-Blo 600VAC 300VDC 20000A Interrupting Rating

The FLSR Series from Littelfuse offers an innovative solution with its individual fused combination motor controllers, designed for accurate and reliable performance in industrial applications. Automated and precision-manufactured components ensure a consistent response to overloads and short circuits, making these controllers an essential choice for the protection of fully-rated panelboards, load centers, and motor control centers. With a remarkable interrupting rating of up to 200,000 A.I.R., these devices provide superior short circuit protection, outpacing traditional non-current limiting mechanical devices. Whether for service entrance switches or other general-purpose circuits, the Slo-Blo/time lag characteristics of these industrial cartridge controllers enhance their effectiveness in diverse applications, from distribution panelboards to switchboard mains and feeder switches.
