The TLP76MSGB ECO-Surge 7-Outlet Surge Protector protects more than just your vital electronics. It's an ideal green protection solution for your bottom line and the environment. Its energy-saving outlet configuration reduces waste (and costs) by cutting AC power to devices that aren't being used.One NEMA 5-15R outlet is always on for a device that requires constant power, such as a router or DVR. The other six NEMA 5-15R outlets have individual on/off switches, so if you aren't using the device plugged into it, you can power off the outlet to save energy. Another illuminated on/off switch provides one-touch control to all outlets except the one that is always on. Recommended for your home or office, the ECO-Surge Protector features 1080 joules to defend your components against even the strongest surges and spikes. Because residential power outlets have three wires—hot line (H), neutral (N) and ground (G)—the TLP76MSGB protects all three, covering the two protection modes: full normal mode (H-N) and common mode (N-G/H-G). It also filters out electromagnetic interference (EMI) and radio frequency interference (RFI) that can disrupt your electronics and inflict hardware damage or data loss. An integrated circuit breaker protects all outlets and automatically shuts down connected equipment in case of overload. The 6-ft. (1.83 m) AC power cord with NEMA 5-15P plug allows the black surge protector to reach distant outlets.
