LSP10 Thermally Protected Varistor Modules are designed for use in outdoor and commercial LED lighting fixtures for transient over-voltage protection. Constructed with Littelfuse thermally protected varistors, they provide robust surge current handling capability and offer quick thermal response due to a thermal disconnect in close proximity to the MOV body.

These modules have UL 1449 3rd Edition Type 4 recognition and are compliant with IEC61643-11 Class II and EN61643-11 Type 2. They meet ANSI/IEEE C62.41.2 Location Category C High Exposure and US Dept of Energy MSSSLC LED Roadway Luminaries Model Spec, Elevated Electrical Immunity requirements.  The LSP10 is offered in series connection wiring configuration.

LSP Thermally Protected Varistor Modules are designed specifically for outdoor and commercial LED lighting applications. Their built-in thermal disconnect function provides additional protection from catastrophic failures and fire hazards, even under the extreme circumstances of MOV end of life or sustained over-voltage conditions. LSP10 modules are replaceable.
