blade terminal & special purpose fuses 463 www.littelfuse.com surge fuses LVSP series surge fuse the littelfuse varistor surge protection (LVSP) fuses are intended for the protection of tvss products. the LVSP series has been designed to survive the 8x20? lightning surges described in various standards (ul1449, iec61000-4-5 & ieee c62.41) without opening. this allows the tvss to perform the necessary suppression. the LVSP series is not rated for continuous current and the ratings are to specific 8x20? surge capability. the LVSP series can be used to facilitate tvss module com- pliance to ul1449 in permanently connected applications (abnormal overvoltage, unlimited current conditions) features: ? rated at 600 vac - 200ka i.r. ? available in surge ratings from 5-100ka (8x20?) ? very current limiting under ac short-circuit conditions ? available in cartridge, bolt-in and pc board mount versions ? provides short circuit protection in tvss systems and complements the littelfuse line of overvoltage products (ha, hb34, tmov and itmov varistors as well as the ak-10 series tvs diodes) agency approvals: recognized under the components program of underwriters laboratories for special purpose fuses. agency file numbers: ul e71611 ratings: 5-100ka 8x20? surge withstand 600vac 200ka i.r. applications: ? tvss products ? surge arrestors recommended fuse blocks for LVSP fuses: ?
