LSP10 Surge Protection Modules

Littelfuse LSP10 Surge Protection Modules offer protection up to 20kA. The LSP10 is a thermally self-protected device specially designed for outdoor and commercial LED lighting fixtures for transient overvoltage protection. Using Littelfuse varistor technology, its built-in thermal disconnect function provides additional protection to prevent catastrophic failure and fire hazard even under the extreme circumstances of varistor end-of-life or sustaining overvoltage conditions. LSP10 Series connected option allows clear indication of thermal fault protection by disconnecting power to the luminaire.
