LED Lighting Surge Protection Modules
EXTEND THE
LIFETIME
OF YOUR LED LIGHTING WITH
RELIABLE SURGE PROTECTION
Maximum Surge
Protection for
Outdoor LED Lighting
The Littelfuse Surge Protection Modules
are self-protected devices that can be used
in outdoor and commercial LED lighting
fixtures for transient overvoltage protection.
They are constructed with Littelfuse
thermally protected varistor technology.
The built-in thermal disconnect provides additional protection
against catastrophic failure/fire hazard under varistor endof-life or sustained overvoltage conditions. The LSP product
series facilitates surge immunity compliance to IEEE C62.41.2
Location Category C High Exposure, ANSI C136.2, and US
Dept of Energy MSSLC Model Spec.

Features
Benefits
• Maximum lightning surge current 20kA
• Thermally protected varistor technology
• Optimized surge immunity solution to protect the outdoor LED fixture investment to get the long term reduction in maintenance costs and energy savings. Without surge protection, the value proposition of LED lighting is at risk
• Thermal fail-safe protection to prevent a hazard to the light or facility due to ‘end-of-life’ or extreme failure conditions of internal components
• Series Version – Clear indication for SPD module
replacement by turning luminaire off when the thermal
fail-safe protection is activated
Parallel Version – External wire option for LED indication
or adaptive lighting circuit
• Confidence in the quality and integrity of specifications will be met since it is subjected to regular, independent 3rd party analysis
• Surge protector is less susceptible to damage from water or environment
• Flexibility to select optimal protection for each lighting installation input voltage
• Parallel-connected and
series-connected options
• Complies with UL1449/IEC61643-111
• Ingress protection IP66
• Wide operation voltage 120Vac~480Vac
