What are these ? These industrial grade 25 Amp
filters sit between your wall plug (110 VAC) and your equipment and stop electromagnetic (EM) noise from getting into the lines. They eliminate noise generated by high current machinery turned ON / OFF or high peak currents generated by short pulses to get into the AC Lines and disturb computers or other equipment in the building.
