Overview Premium protection for essential network workstations, telecom systems, point-of-sale equipment and audio/video systems, the ISOBAR825ULTRA Isobar 8-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. In fact, Tripp Lite will repair or replace any connected equipment damaged by surges, including direct lightning strikes, up to $50,000 for life (valid in the U.S., Canada and Puerto Rico only). The ISOBAR825ULTRA features eight widely spaced NEMA 5-15R outlets, which are arranged in four exclusive isolated filter banks that prevent equipment connected to one bank from interacting with equipment connected to another. 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 wireshot line (H), neutral (N) and ground (G)the ISOBAR825ULTRA protects all three, covering two protection modes: full normal mode (H-N) and common mode (N-G/H-G). Included safety covers protect against dust while blocking accidental contact with unused outlets. An integrated 12A circuit breaker protects all outlets and shuts down connected equipment in the event of an overload. A lighted on/off switch provides one-touch control over connected components. Diagnostic LEDs show power, protection and line fault status at a glance. An extra-long 25-foot cord with right-angle 5-15P plug reaches distant outlets and allows furniture to placed flush against the wall.
