Littelfuse LSP Series LED Surge Protection Modules

Product Description

Littelfuse LSP05 and LSP10 SPD Modules are the world’s first series-connected, 20kA-capable, indicating surge arrestors for outdoor lighting applications.

These self-protected devices, based on Littelfuse thermally protected varistor technology, can be used in outdoor and commercial LED lighting fixtures for transient overvoltage protection.

The built-in thermal disconnect provides additional protection against catastrophic failure/fire hazard in the event of varistor
end-of-life failure or sustained overvoltage conditions.

The LSP05 device is configured with parallel connections. It features an indicator wire that can activate an LED to tell maintenance personnel when to replace the SPD.

The LSP10 is available with either parallel or series connections. With the parallel-connected version, an indicator wire can activate an LED to tell maintenance personnel when to replace the SPD. The series-connected version cuts luminaire power off to provide a clearly visible indication that the SPD should be replaced.
