330 Joules of Surge Suppression

The ISOBAR4/220’s 330-joule surge suppression rating keeps your valuable equipment protected from electrical surges, spikes and noise interference originating both outside and inside your building. It uses robust surge suppression circuits with sine wave tracking to offer extreme levels of protection against the heaviest surge conditions exceeding IEEE 587 category A & B specifications.

Exclusive Isolated Filter Banks with Advanced Noise Filtering Technology for Ultimate Performance

The Isobar is the only surge protector line 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. Isobar's unique protection system combines large toroidal chokes, ferrite rod-core inductors, HF/VHF capacitors and multiple layers of metal oxide varistors into two exclusive isolated filter banks that remove EMI/RFI interference and prevent system crashes, reboots and performance problems.

Versatile Installation Options

The ISOBAR4/220’s 6 ft. (1.8 m) cord reaches distant outlets. A space-saving, right-angle plug allows office furniture and cabinets to be placed flush against the wall. The case is equipped with keyhole mounting slots to facilitate permanent installation on walls, under counters, on worktables and other flat surfaces.


Lifetime Warranty and Environmentally Responsible Design

For peace of mind, the ISOBAR4/220 comes backed by a lifetime warranty. The ISOBAR4/220 is also manufactured in compliance with strict RoHS specifications, reflecting Tripp Lite’s commitment to environmental responsibility.
