Compact surge protection

The Tripp Lite SK3-0 is a direct plug-in surge suppressor with three NEMA 5-15R outlets and a 660 joule rating. It handles 120V AC input and supports up to 1875 watts of connected equipment. Diagnostic LEDs show protected and grounded status at a glance.

Wall-mount convenience

The unit plugs straight into a wall receptacle, adding three outlets without a cord or power strip footprint. Full normal mode and common mode suppression cover hot-neutral, neutral-ground and hot-ground lines. It frees up space on desks or behind furniture where a traditional strip would not fit.

Step up from basic power taps

This protector replaces unprotected multi-outlet adapters that offer no surge energy absorption. The 660 joule rating and UL1449 3rd Edition certification mark a clear upgrade for shielding computers, routers or chargers. Buyers needing higher joule counts or additional outlets should consider larger models.

Questions about this item

How much surge energy can the SK3-0 absorb before its protection degrades?

The unit is rated at 660 joules of surge suppression, which is the total energy it can absorb over its lifetime before the protective components wear out.

Does the direct plug-in design generate noticeable heat or noise when powering devices continuously?

It has no fan or moving parts, so it runs silently and produces only minimal warmth from the internal suppression circuitry under normal load.

What type of wall receptacle is required for the SK3-0 to function properly?

It plugs directly into a standard NEMA 5-15R grounded outlet supplying 120 V AC and requires a valid ground connection for the protection modes to operate.
