Compact four-outlet surge strip

The Tripp Lite TLP404 provides four NEMA 5-15R outlets in a light-grey plastic housing. It accepts 120 V AC input and delivers up to 15 A or 1800 W total. A 450-joule suppression rating and 150 V clamping voltage protect connected equipment from line transients.

Keyhole mounting and four-foot cord

Keyhole slots on the back allow wall or under-desk installation without tools. The 4 ft cord with NEMA 5-15P plug reaches nearby sockets while keeping the strip close to gear. A diagnostic LED confirms active protection and a 15 A resettable breaker cuts power during overloads.

Replaces basic power strips without suppression

This unit upgrades plain outlet strips that lack joule-rated surge clamping and EMI/RFI filtering. The jump is worth it when protecting computers, networking gear or home-office electronics from everyday voltage spikes. It does not suit installations needing more than four outlets or higher joule ratings.

Questions about this item

What does the 150 V RMS clamping voltage mean for the 120 V AC circuit?

It limits transient spikes to roughly 150 volts RMS, diverting excess energy above the normal 120 V supply level through full normal and common mode paths.

What mounting option does the keyhole style on the 1.20" x 1.85" x 8.10" housing provide?

Two keyhole slots on the back accept #6 or #8 screws for flush wall or under-desk mounting without brackets.

How do I install the unit so the diagnostic LED correctly confirms surge protection status?

Plug the NEMA 5-15P cord into a grounded 120 V receptacle, press the resettable 15 A breaker if tripped, and verify the LED lights solid green.
