Ultimate Protection for All Electronics
The IBAR4 offers powerful surge protection for all electronics. It provides four AC outlets arranged in two isolated filter banks. Outlets are widely spaced to accommodate up to two large transformers without blocking remaining outlets. A set of 4 plug-in covers is included to safeguard unused outlets. A 6-ft. cord enables connection to a distant wall outlet and a space-saving right-angle plug allows furniture to be placed flush against the wall. An illuminated master switch provides one-touch power control over all connected components. Four keyhole slots on the back of the unit enable the IBAR4 to be wall mounted.

Powerful Surge Suppression and Performance Enhancement

Powerful Surge Suppression and Performance Enhancement
More joules mean more protection! The IBAR4's 3330-joule surge suppression rating, Isobar surge protection technology and rugged all-metal housing shield connected equipment from even the strongest surges. EMI/RFI line noise filtering helps components perform at their peak. Line noise filtering eliminates performance problems that can be caused by radio transmissions, fluorescent lighting and appliances, while promoting longer component life spans.

Exclusive Isolated Filter Banks
Devices connected to the same surge suppressor can interfere with one another's performance—for instance when office equipment or household appliances (printers, copiers, blenders, vacuums, fans) degrade TV picture and sound quality. The Isobar is the only surge suppressor with internal barriers (called isolated filter banks) that prevent disruptive line noise from causing A/V distortion, computer lock-ups, data errors and similar problems. Isolated filter banks ensure that peripheral devices and appliances don't degrade the performance of computers and sensitive A/V components.

The case is equipped with four keyhole mounting slots to facilitate permanent installation on or under counters and worktables, on walls, etc. Included outlet covers (set of four) may be used to safeguard unused outlets.

Ultimate Peace of Mind
The IBAR4 comes with $50,000 Ultimate Lifetime Insurance coverage for connected equipment—guaranteed lifetime protection against damage due to surges, including direct lightning strikes. Ultimate Lifetime Insurance coverage begins the moment you purchase your Tripp Lite surge suppressor—no forms to fill out or send in!

Tripp Lite's ISOBAR is the world's #1 selling premium suppressor series with more than 14 million satisfied customers and a safety-tested history of 20+ years
Robust surge suppression with sine-wave tracking protects against the heaviest of surge conditions, exceeding IEEE category A&B specifications and reducing 6,000V test surges to harmless levels less than 35 volts.
Multi-component suppression circuits combine torroidal chokes, ferrite rod-core inductors, HF/VHF capacitors and multiple layers of metal oxide varistors into exclusive isolated filter banks that remove EMI/RFI interference, even noise from other pieces of connected equipment.
4 outlets arranged in two filter banks prevent system crashes, reboots and performance problems common as noisy peripherals are powered off and on.
Network grade surge suppression rated at 3330 joules / 85,000 amps
Widely spaced outlets accommodate up to 2 large transformer plugs without blocking outlets
