Littelfuse LSP05 & LSP10 Surge Protection Modules

Littelfuse LSP05 & LSP10 Surge Protection Modules

Littelfuse LSP05 and LSP10 Surge Protection Modules are the industry's first series connected, 20kA capable indicating surge arrestors for outdoor lighting applications. LSP10 can provide up to 20kA protection module maximum lighting surge current and LSP05 provides up to 10kA. 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.
