Littelfuse LSP05 & LSP10 Surge Protection Modules

Littelfuse LSP Surge Protection Modules

Littelfuse LSP Surge Protection Modules are used in surge protectors and are built with high-quality, dependable materials. The LSP05 and LSP10 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 LSP05GX is used in European outdoor and commercial LED lighting fixtures for transient overvoltage protection. 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.

Littelfuse LSP05GX thermally protected Surge Protective Device is a self-protected device specially designed to be used in European outdoor and commercial LED lighting fixtures for transient overvoltage protection. It has been developed with Littelfuse's thermally protected varistor technology. Its built-in thermal disconnect function provides additional protection to prevent catastrophic failure and fire hazard even under extreme circumstances of varistor end-of-life or sustaining over voltage conditions. It also provides high line-to-earth/ground resistance, facilitating faster production line testing.

LSP05GX series connected option allows clear indication of thermal fault protection by disconnecting power to luminaire, thereby signaling SPD module replacement. The LSP05GX Surge Protective Device facilitates compliance to IEEE C62.41.2 Location Category C Low.


Features
  • Meets IEEE C62.41.2 Location Category C Low Exposure and ANSI C136.2 Enhanced Level Specs
  • Thermally protected varistor technology
  • Parallel-connected and series-connected options
  • UL 1449 recognized and EN/IEC61643-11 Class II compliance
  • High line-to-earth/ground resistance
  • Option for Class II unearthed luminaire installation, common in Europe
Applications
  • Digital Signage
  • Flood Lighting
  • Parking Garage Lighting
  • Roadway Lighting
  • Street Lighting
  • Traffic Lighting
  • Tunnel Lighting
  • Wall Wash Lighting
