Thermally protected SPD 10kV/5kA surge protection module

Littelfuse introduces a new series of thermally protected surge protective devices that provide robust transient overvoltage protection for outdoor and commercial LED lighting fixtures.

The LSP05GI Series LED Lighting Surge Protection Module is capable of providing 10kV/5kA surge protection and is certified to IEC/EN 61643-11. Its surge handling capability enhances an LED lighting fixture’s surge immunity and extends its operating lifetime.

Littelfuse thermally protected varistor technology guards against hazards affecting a light or a facility due to 'end-of-life' or extreme surge conditions. It is available in both parallel-connected and series-connected formats. The series connection option disconnects the power to protect the luminaire; the parallel connection disconnects itself at end-of-life and keeps the luminaire powered.

Applications include roadway lighting, parking garage lighting, wash wall lighting, traffic lighting, flood lighting, digital signage, tunnel lighting, and street lighting.

LSP05GI Series LED Lighting Surge Protection Modules offer these key benefits:

* IEC 61643-11 and EN61643-11 certification of these modules allow luminaire manufacturers to meet IEC/EN 60598-1, the international testing standard for luminaires

* Double-insulated cable wire makes them suitable for use in luminaires designed for Class I and Class II installations

* A built-in LED indicator alerts maintenance personnel to the need for replacement.
