Protecting electrical equipment from transient voltage surges prevents outages and reduces maintenance. Littelfuse offers several surge protectors to limit damage from lightning and overvoltage that may occur when equipment is switched on. Our varistor modules provide overvoltage protection for outdoor equipment and LEDs. Our globally compliant Type 2 SPDs plug in to generators, motors, and telecom and computer equipment. Consult our Surge Protection Devices Catalog to find your best solution.

What Are Surge Protection Modules?
LSP05 & LSP10 Thermally Protected Varistor Modules are designed for use in outdoor and commercial LED lighting fixtures for transient overvoltage protection. Constructed with Littelfuse thermally protected varistors, they provide robust surge current handling capability (Max Single Surge Current, 10kA@8/20us and 20kA@8/20us) 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. Both LSP05 and LSP10 are provided with parallel connections. The two parallel connection modules offer monitor indication wire options. The LSP10 is also available in series connection option.
What does a Surge Protective Module Do?
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 overvoltage conditions. LSP05 and LSP10 modules are replaceable. The LSP10 series-connected version has a special indication function that turns the light off when it is activated.
Where Can Surge Protective Modules Be Used?
- Outdoor and commercial LED lighting fixtures
- Roadway lighting
- Digital signage
- Service entrance lighting and parking garage/lot lighting
- Flood lighting and tunnel lighting
- LED signage and traffic lights
What Are Surge Protective Devices?
The SPD2 Series of Type 2 Surge Protective Devices (SPD) are for branch circuits to safeguard components from transient overvoltage or surges. The majority of these incidents are caused by turning equipment on and off such as motors, generators, controllers, building management systems, and HVAC or medical equipment. The SPD2 Series limits the fault current to a load or the unit to protect it from harm.
The LSP Thermally Protected Varistor Module is replaceable and protects the lighting fixture/luminaire from damage due to transient overvoltage and overheating, reducing maintenance costs and extending luminaire lifetime. The indication wire can be connected to an indication circuit for light monitoring purposes.

What is ANSI/UL 1449?
ANSI/UL 1449 is the standard required to List (or Recognize) a Surge Protective Device or component to Underwriters Laboratories, LLC specifications for safety and performance. UL labels are required on every UL Listed or Recognized SPD, indicating Voltage Protection Ratings (VPR), Short Circuit Current Rating (SCCR), the type of SPD, the Maximum Continuous Operating
What is the difference between the terms “Surge Arrester”, “Transient Voltage Surge Suppressor (TVSS)” and “Surge Protective Devices (SPD)”?
Up until the 3rd edition of UL 1449 – Standard for Surge Protective Devices was introduced in 2006 (compliance required in 2009), there were various terms used when referencing devices intended to limit the effects of a surge event. Surge arresters were originally developed for the line side of power distribution systems, protecting the system structure and not
What do the various product markings on an SPD mean? Why are they important?
Underwriters Laboratories (UL) requires certain markings be on all listed and recognized SPDs. * SPD Type – Describes the intended location of the SPD in regard to the main breaker * Type 1 – Between the secondary of the service transformer and the line side of the main breaker * Type 2 – Permanently connected SPD on the load side of the main breaker * Type 3 –
