Keep Lexmark laser printers and MFPs online when electrical conditions turn unpredictable. The Lexmark Surge Protective Device 120V is designed to defend connected equipment from both power line and phone/fax surges, helping preserve print availability and reduce avoidable service calls. Built for Lexmark’s printer environment, this model adds protection where lower-cost surge strips fall short. The upgraded circuit board uses thicker two-ounce copper plating for improved electrical handling, while double-layer component insulation helps manage heat. A flame-resistant enclosure and thermal cut-off fuses add another layer of protection by reducing the chance of short circuits and limiting fault propagation. The integrated five-foot IEC appliance coupler cord supports straightforward placement near the device it protects. With 120 V AC input and data-line protection for phone/fax connections, this surge protective device is a practical fit for offices that depend on consistent output from shared print infrastructure. For teams protecting higher-value Lexmark hardware, it delivers the kind of electrical defense that helps justify the investment in the printer itself.
