Sphere-Shaped 3-Outlet Surge Protector Safeguards Your Sensitive ElectronicsIdeal for your home or office workstation or travel use, this Safe-IT™ power ball features a surge suppression rating of 540 joules to defend your sensitive electronic components against even the strongest power surges and spikes. Because residential power outlets have three wires-hot line (H), neutral (N) and ground (G)-the TLP38UAM protects all three, covering the two protection modes: full normal mode (H-N) and common mode (N-G/H-G). NEMA 5-15R Outlets Accept a Wide Range of Electronic DevicesPlug your laptops, projector, printer and other conference-table electronics into three NEMA 5-15R outlets to protect them against dangerous surges, spikes and line noise. The outlets offer easy 360-degree access to power and are located on different sides to accept bulky transformers without blocking adjacent outlets. USB Ports Share 4.8 Amps of Charging PowerFour USB-A ports are available for charging your smartphones, tablets and other USB mobile devices. They share 4.8A of charging power, which is plenty for delivering ample power to demanding devices. Filtering EMI/RFI Line Noise Helps Your Equipment Perform BetterThis surge protector filters out disruptive electromagnetic and radio frequency interference that can inflict hardware damage or data loss. This EMI/RFI filtering also helps your connected components perform better and last longer. Antimicrobial Protection Helps Provide a Safer, Cleaner and Healthier Work EnvironmentThe Safe-IT TLP38UAM features antimicrobial protection that helps resist the growth of bacteria, viruses, fungi, mold and mildew. Premium Safety Features Protect Your Valuable EquipmentAutomatic shutoff permanently cuts power to outlets if the protection circuit is incapacitated, preventing equipment damage and indicating replacement is required.
