The ASCO Model 235 surge protector is a compact submersible device that is designed to be installed directly within a light pole to help protect the sensitive lighting ballast and power supply from damaging transients. Model 235 easily fits into the 3 in. x 5 in. hand hole located at base of the light pole and is wired in series with the load.

Model 235 contains a green status LED that will go out if the unit is not fully functional. This aids maintenance personnel in identifying if the unit needs to be replaced.
