Premium protection for your expensive computer and audio/visual equipment, the ULTRABLOK Isobar® 2-Outlet Surge Protector features a surge protection rating of 1410 joules to defend your sensitive electronics against even the strongest surges and spikes. In fact, Tripp Lite will repair or replace any connected equipment damaged by surges, including direct lightning strikes, up to $10,000 for life (valid in the U. S., Canada and Puerto Rico only). The ULTRABLOK features two NEMA 5-15R outlets, perfect for your flat-panel HDTV and Blu-ray player or a pair of computer peripherals, such as a printer and a router. This unit's unique protection system prevents disruptive line noise from causing A/V distortion, computer lock-ups, data errors and similar problems. Large toroidal chokes, ferrite rod-core inductors, HF/VHF capacitors and multiple layers of metal oxide varistors remove EMI/RFI interference and prevent system crashes, reboots and performance problems. Because residential power outlets have three wires-hot line (H), neutral (N) and ground (G)-the ULTRABLOK protects all three, covering two protection modes: full normal mode (H-N) and common mode (N-G/H-G). An integrated 15A circuit breaker protects all outlets and shuts down connected equipment in the event of an overload. Diagnostic LEDs show power, protection and line fault status at a glance. The ULTRABLOK plugs directly into any standard NEMA 5-15R outlet. Optional mounting hardware is included for permanent attachment to the outlet cover, which will prevent the ULTRABLOK from coming loose accidentally. More from the Manufacturer
