Tripp Lite's 6-Outlet Surge Protector with USB Charging Safeguards Your Sensitive Electronics. Ideal for your home or office workstation or home theater, this Protect It! 6-outlet surge protector features a surge suppression rating of 900 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 TLP64USBRA15 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 Devices. Plug your PC, printer, wireless router, game console, television, sound system or other home/office electronics into six NEMA 5-15R outlets to protect them against dangerous surges, spikes and line noise. Two outlets are set apart from the others to accept bulky transformers without blocking adjacent outlets. 4 USB Ports Share 4.2 Amps of Charging Power. Four USB-A ports are available for charging your smartphone, tablet and other USB mobile devices. They share 4.2A for charging multiple devices at the same time. Premium Protection from EMI/RFI Line Noise Helps Your Equipment Perform Better Various electromagnetic and radio sources found in virtually every home and business can cause disruptive interference on the AC line. Known as EMI (electromagnetic interference) and RFI (radio frequency interference), this line noise is a common cause of performance problems. This surge protector filters out disruptive line noise that can disturb your electronics and inflict hardware damage or data loss. This EMI/RFI filtering also helps your connected components perform better and last longer. Premium Safety Features Protect Your Valuable Equipment. The lighted on/off switch provides one-touch control over connected equipment. A 15A circuit breaker protects all outlets and automatically cuts power if the protection circuit is incapacitated, preventing equipment damage. A green LED confirms your connected equipment is protected. Versatile Surge Protector Provides Multiple Installation Options.This surge protector with 15-foot cord and space-saving right-angle NEMA 5-15P plug allows you flexibility in placing the unit away from a wall outlet or behind furniture. Keyhole slots incorporated into the bottom panel provide convenient wall or desk mounting options for the black plastic housing.
