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 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.

AGENCY FILE NUMBERS: UL E71611
