Zero Surge Inc.’s Tru-Block surge protection products minimize let-through voltage levels (330V or less) to safeguard sensitive electronics and will suppress surge current, voltage and duration over a wide voltage range (175V maximum continuous operating voltage), which can prove especially beneficial during brownouts, power failures or when generators are in use. The line consists of panel-mount products for surge protection for one or more entire rooms, including dual models for 20 A, 120V or 20 A, 240V applications. Plug-in versions (15A capacity) offering two or eight outlets (depending on model) also are available.
