Loaded with a generous combination of high quality components, near indestructible all-metal case and unique noise filtration system, the isobar offers the highest level of protection attainable in a multi-outlet strip. Robust surge suppression circuits with sine-wave tracking offer extreme levels of protection against the heaviest surge conditions exceeding IEEE 587 category A & B specifications and reducing 6,000V test surges to harmless levels under 35 volts. Isobar's unique protection system combines large toroidal 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 generated by other pieces of connected equipment. IBAR4 offers 4 outlets arranged in two filter banks to prevent system crashes, reboots and performance problems common as noisy system peripherals are powered off and on. Surge suppression rated at 3330 joules / 85,000 amps offers network-grade protection. Widely spaced NEMA5-15 outlets accommodate up to 2 large transformer plugs without blocking outlets. Includes 6 ft. AC line cord with space-saving angled input plug and keyhole mounting tabs.

Rated 4.5 out of 5 by 11 reviewers.
Rated 5.0 out of 5.0 by This thing is a tank In 2000 I was working for a IT company, who deployed only these to their clients. The others I worked with swore by them. I purchased one, and, today, 15 years later, the only thing wrong with it is that the light in the lighted switch burned out. However it continues to protect and provide power without a hum or any problems at all. It really is a tank. February 11, 2015
Rated 5.0 out of 5.0 by Best protection! ISOBAR is a premium surge protection product. I have tried many UPS's and surge protection products. UPS units are good to use, especially if you work/live in an area where power fluctuations or outages occur frequently. However, UPS units have batteries that eventually need to replaced. UPS's are a tad more expensive and do not over the same joule/surge rating. The metal housing on the ISOBAR is indestructible, fire-safe, and features multiple isolated filter banks with quality surge absorbing components. The Ultra 4 has a rating of 3330 Joules (the greater the number, the better it is) and costs less than comparable Belkin, APC, and/or brands. TRIPPLITE makes other solid products; ISOBAR is the pinnacle in surge protection. November 6, 2012
Rated 5.0 out of 5.0 by Protecting My Electronic Equipment for Decades I learned about Tripp-Lite surge protectors when I worked as a Computer Systems Field Service Engineer over 15 years ago. I visited customer sites where major power-line disturbances had occurred. Some Isobar surge protectors had failed - when they stopped lightning strikes (!), but whatever had been plugged into them remained unscathed. When it came time to specify power protection for my workshop and studio I selected Tripp-Lite Isobar Surge Protectors. I have had no reason to doubt my selection, and it has been over a decade.

Rated 5.0 out of 5.0 by Excellent Product & Warranty I bought my first IBAR4 in the 1980's when I got my first computer while working at a software company. This is the one they recommended and I have never regretted it. When the original one from the 80's died, it was only a phone call and it was replaced under the lifetime warranty - I was ecstatic. We now live in a rural area with less than stellar electric service with many surges. Nothing has gotten through this surge protector. Highly recommend. September 16, 2013
Rated 5.0 out of 5.0 by Surge Protection For Mobile Stage Lighting Music Entertainment. I use two Tripplite ISOBAR's to surge protect my mobile stage lighting system. As my lighting system is transported to multiple venues, power surge conditions are always a concern. Worry free ISOBAR operation allows focus on lighting performance. Nice long six foot cord allows ISOBAR's to be located away from walls and placed exactly where needed. Excellent quality heavy duty metal housing box take the regular transportation demands of a mobile lighting system. Highly recommended. December 6, 2012
Rated 3.0 out of 5.0 by Two Problems I received the IBAR4 today and immediately discovered two problems. First, the serial number on the unit did not match anything on the web site tutorial for locating the serial number. Second, I expected a heavy duty ground lug, but the only ground connection is an unlabeled small silver screw on the end of the unit where the power cord enters. Furthermore, there is no mention of this screw in the owner's manual. I had to call support to get answers to both issues. March 26, 2012
Rated 5.0 out of 5.0 by This product is indestructible. The product has been kicked, dropped, pulled, and etc. I have had the product for about a year and few power outs. The equipment that is plugged into it is still running. This is the one thing my internet company did right. They recommended this product. September 6, 2013
Rated 5.0 out of 5.0 by A rare product with a solid warranty Here is my very simple and solid experience with the ISOBAR-4 product. I bought the product more than 12 years, never had any equipment failure due to power during that time, 10 years into the ownership, the switch on the product no longer work properly due to the many on/off cycle this product has been experiencing on a daily basis (connected to my primary PC that is turned off and on on a daily basis via the switch). I submitted a request to TRIPP-LITE for replacement, all I needed to provide was the product model and serial number and ship back the defect product, a new replacement was in my hands a few days later. Such excellent replacement policy after more than 1 decade owning the product, there is simply no comparison. Since then, I have purchased one additional 6 outlet ISObar product without reservation to protect my home theater system, because I know I can count on the product to always be there when I need it, just solid solid product support. Couldn't ask for more. December 8, 2011
