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 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 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 (8x20μs)
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.
