Surge protection modules boast IP66 waterproof design

New surge protection modules LSP05 and LSP10 developed by Littelfuse are now available at distributor Rutronik. Constructed with Littelfuse thermally protected varistors, they provide robust surge current handling capability for outdoor and commercial LED lighting fixtures. One of the modules includes world’s first series-connected, 20kA-capable indicating surge arrestor.

The LSP05 Series with maximum lightning current ratings of 10kA is configured with parallel connections, whereas the LSP10 Module is available with either parallel or series connections. This series-connected version is the world’s first indicating surge arrestor capable of handling surges of up to 20,000A.

It cuts luminaire power off to provide a clearly visible indication the SPD (Surge Protection Device) should be replaced. With the parallel-connected versions, an indicator wire can activate an LED to tell maintenance personnel when to replace the SPD in order to ensure the luminaire remains protected.

Both product lines, in the compact form factor of 48 x 48 x 30mm, come with a built-in thermal disconnection function that provides additional protection from catastrophic failures and fire hazards, even under extreme circumstances of varistor end of life or sustained overvoltage conditions.

The modules target applications, in outdoor and commercial LED lighting like roadway lighting, traffic lighting, digital signage, service entrance lighting, parking garage/lot lighting, as well as flood, tunnel and street lighting.

IP66 water- and dust-proof designs enables flexibility in outdoor locations, inside or outside of luminaire, top or bottom at lighting pole, in transformer boxes or on distribution panel.
