Low Voltage Arrestors 120V-480V

SKU: Low Voltage Surge Suppression Devices Category:


Lightning Master manufactures a full line of AC power surge suppressors for industry and commercial applications. Most manufacturers offer specific units for each voltage. This creates an installation problem, as few end users know the actual voltage they need. A Customer may say he has 480V service, when he actually has 277/480V 3Φ Y service. If the installer shows up with a 480V surge suppressor, he cannot complete the installation. Lightning Master solved that problem by addressing all operating voltages with only three different series, plus two additional snap-in modules for high-leg services.
