Premium protection for essential network workstations, telecom systems, point-of-sale equipment and audio/video systems, the IBAR12-20T Isobar 12-Outlet Surge Protector features a network-grade surge protection rating of 3840 joules to defend your sensitive electronics against even the strongest surges and spikes. The IBAR12-20T features 12 total outlets -- two front NEMA 5-15R and 10 rear NEMA 5-20R -- which are arranged in two exclusive isolated filter banks that prevent equipment connected to one bank from interfering with equipment connected to the other. These internal barriers also prevent 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 IBAR12-20T protects all three, covering two protection modes: full normal mode (H-N) and common mode (N-G/H-G). An integrated 20A circuit breaker protects all outlets and shuts down connected equipment in the event of an overload. A lighted on/off switch with locking cover provides one-touch control over connected components. Diagnostic LEDs show power, protection and line fault status at a glance. The IBAR12-20T mounts to a wall, under a counter or in 1U of rack space using the included hardware. A 15' (4.6m) power cord reaches distant outlets, and a locking L5-20P plug ensures that the IBAR12-20T stays connected to your power source.
