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.
