Network-Grade Surge Protection

The Tripp Lite ISOBAR12ULTRA is a 12-outlet surge protector rated for 3840 joules and 1800 watts at 120 V AC. A 15-foot NEMA 5-15P cord feeds an all-metal 1U cabinet that can be rack-mounted, wall-mounted or placed under a counter. Diagnostic LEDs confirm protection status and line-fault conditions.

Ideal for Dense Rack or Workstation Setups

The unit suits installers who need twelve NEMA 5-15R receptacles in a single 1U space with 40–80 dB EMI/RFI filtering across H-N, N-G and H-G modes. Buyers who require 20 A circuits, higher joule ratings, or non-NEMA outlet types should look elsewhere.

3840-Joule Suppression Rating

The AC suppression joule rating of 3840 joules is the single figure that determines how much surge energy the device can absorb before its protective components degrade. Match this number to the exposure level of the connected equipment.

Questions about this item

Will the 15-foot cord and 12 NEMA 5-15R outlets let me keep my older 120 V gear plugged in without extra adapters?

Yes — the unit supplies 120 V AC through 12 standard NEMA 5-15R outlets on a 15-foot cord, so legacy 120 V devices connect directly.

How do I confirm the 3,840-joule surge protection and 40–80 dB noise filtering are active after installation?

Diagnostic LED indicators on the front panel show protection status and line-fault conditions so you can verify operation at a glance.

What mounting hardware is included and what must I source separately for a 19-inch rack?

Detachable mounting flanges for 1U rack, wall or under-counter mounting are included; rack screws and cage nuts are not supplied.
