The Littelfuse Varistor Surge Protection (LVSP) Fuses are intended for the protection of TVSS products. The LVSP Series has been designed to survive the 8x20µs 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 8x20µs surge capability. The LVSP Series can be used to facilitate TVSS module compliance to UL1449 in permanently connected applications (abnormal overvoltage, unlimited current conditions)
