Edco SHAS-120 120V Surge Protector Highway Lighting Pole.
SHAS-120 Surge Protector.
The Emerson Edco SHAS-120 120V Series Highway Lighting Protector is a smaller version of the popular Edco SHA Series. It easily fits into a outdoor light pole 3" x 5" hand hole and incorporates the use of TMOV's (MOV's with a thermal cutoff) and an LED. Should the unit's TMOV's degrade as a result of either a large surge or over time due to multiple surges, the LED will go out. This will enable the maintenance personnel to easily identify if the protection is lost and the unit needs replacing. The Edco SHAS Series also has about 30% less capacitance, thus eliminating the need to require a low capacitance version.
