Ideal for your home, office, retail or industrial workstation, this 120V surge protector features a surge suppression rating of 900 joules to defend your valuable electronic components against power surges and spikes. It plugs directly into a wall outlet, avoiding annoying cord clutter. Diagnostic LEDs alert you to potential wiring or protection faults before connected equipment is damaged. Plug your computer, printer, wireless router, desk lamp and other home/office electronics into 7 NEMA 5-15R outlets to protect them against dangerous surges, spikes and line noise. Automatic shutoff permanently cuts power to outlets if protection circuit is incapacitated, preventing equipment damage and indicating replacement is required. This surge protector filters out disruptive EMI (electromagnetic interference) and RFI (radio frequency interference) 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.
