Essential Surge Protection for Desktop Workstations

The Tripp Lite TLP404 surge suppressor delivers AC 120 V protection for workstations, desktop PCs and telecom systems. It provides four NEMA 5-15 outlets including one designated transformer plug outlet. A four-foot cord and keyhole mounting tabs allow flexible placement. Diagnostic LEDs warn when the suppressor circuitry is damaged.

Practical Limits of 450 Joule AC Suppression

The unit absorbs transient surges up to 450 joules and filters line noise for connected equipment. Once that energy rating is exceeded the protective components can no longer shield downstream devices. The diagnostic LED indicates when the suppressor has been compromised and replacement is required. No battery backup or voltage regulation is provided.

Four Outlets Decide If This Fits Your Desk

With exactly four output connectors the TLP404 suits a single computer plus a few accessories. Builds requiring more than four protected outlets or higher joule ratings for heavy transient environments will need a different unit. The compact 1.5 in by 9.5 in by 1.5 in housing mounts easily in tight spaces.

Questions about this item

Which TLP404 model should I choose for basic surge protection?

The TLP404 is a single model with four NEMA 5-15 outlets, a 450 joule suppression rating and a four-foot cord; there are no alternative versions or capacities listed.

What does the 450 joule rating mean for my connected equipment?

It indicates the total energy the suppressor can absorb from transient spikes before the protection circuit is exhausted; once that energy is reached the unit must be replaced.

What does the NEMA 5-15 interface cap in practice?

Each outlet accepts standard North American 120 V plugs rated up to 15 A, so any device with a compatible plug can be connected within that current limit.
