Comments about Tripp Lite Protect It! 5-Outlet Surge Protector Direct Plug-In 1080 Joules 1-Line RJ11 Protection:

My house was surged by lightening and blew out some of my appliances thru the Ethernet line. So I went on the hunt for surge protectors for everything including my phone line. There are few out there that aren't a strip plug. My phone sits on my kitchen countertop, so I didn't want a strip. I have a 4 socket plug in on the wall and didn't want to lose my access. I love the red and green light system to tell you it still working. They can sometimes take multiple zaps before the unit quits doing its job. This has held up very well. Fits nicely in the spot I needed it.

Comments about Tripp Lite Protect It! 5-Outlet Surge Protector Direct Plug-In 1080 Joules 1-Line RJ11 Protection:

Small post is supposed to fit into the round ground hole in the outlet---EXCEPT it doesn't so the unit doesn't sit flush on the outlet! Other than that unit is great as is everything Tripp-lite makes!

Absolute BEST Surge Suppressor

Comments about Tripp Lite Protect It! 5-Outlet Surge Protector Direct Plug-In 1080 Joules 1-Line RJ11 Protection:

You cannot lose with Tripp Lite! We have constant surges in my area. This surge suppressor takes the surge and no damage comes to my equipment. I have one of these on almost every outlet that I use often. I don't have to worry about losing what is plugged in. I know that Tripp Lite will back up their product if there is a hit on the surpressor. They are very good about replacing the suppressor when a hit comes. My equipment is spared and they send out a replacement suppressor! Can't lose! Before Tripp Lite I was having to buy new suppressors constantly.

Frequently Asked Questions

A surge protector will protect your electronics by acting as an “electrical sponge” by clamping down on spikes, “soaking them up” and converting the excess energy into heat, thus preventing the spikes from passing through the surge protector into the sensitive electronic devices and damaging them. As with any “sponge” a surge protector has a limited absorption capacity. Once that capacity is reached, the unit is no longer able to protect and must be replaced.
The Grounded or Ground OK LED light is present on select Tripp Lite 120V surge products. The purpose of this indicator light is to confirm that the surge protector is connected to a grounded AC source. If the LED is not lit, then the unit is connected to an AC source that is not grounded. To provide the maximum amount of protection, the Tripp Lite surge protector must be plugged into a grounded AC source.

Here are some reasons why the Grounded or Ground OK LED will not light up:

    -Missing ground wire. (Note: This also includes using a 3-prong to 2-prong adapter.)
    -A severe surge has occurred and the unit absorbed the damage, as designed, to protect connected equipment.
    -The LED is malfunctioning.

Follow these instructions to identify the problem:
1. Remove any equipment still connected to the surge protector.
2. Turn off the surge protector.
3. Check to make sure the circuit breaker is reset.
4. Plug the unit into a working and properly grounded 120V AC power source that provides computer-grade power and is on a different circuit than the one originally used.
5. Toggle the master switch to the On position.

If the Grounded or Ground OK LED does not light up, the unit requires replacement.
Your Tripp Lite surge protector is designed to pass power continuously to the electronic devices plugged into it when used under normal operating conditions as instructed in the owner’s manual.

There are several common reasons why the unit may not pass power:

    -Your unit was hit by a power surge, causing the internal components, as designed, to absorb the damage and protect the connected equipment.
    -The wall outlet to which the unit is connected is not passing power.
    -The surge protector is not fully plugged into an AC source.

Follow these instructions in an attempt to restore normal operation:

1. Remove any equipment still plugged into the unit.
2. Unplug the unit from the AC power source.
3. Check the AC power source by plugging in a different device to verify that the outlet is passing power. If the outlet is working, plug in the surge protector. The surge protector requires a working 120V AC power source that provides computer-grade power.
4. Connect a small device, such as an alarm clock or radio, to the surge protector to test if the unit is passing power.

If you followed these steps and the surge protector is still not passing power, then the unit requires replacement.
There are three common reasons why these ports may not be working properly:

    -The phone cords are not connected to the proper jacks on the surge protector.
    -The phone cords are not firmly seated in the phone jacks.
    -A surge has come through and damaged the phone board of the surge protector.

Follow these instructions to determine if the RJ11/phone jacks are functioning properly:
1. Remove the device that is plugged into the RJ11/phone jacks on the surge protector.
2. Plug the device directly into your signal source to verify that it is operating correctly. If the device is not working, contact the device's manufacturer for further troubleshooting assistance. If it is working, proceed to the next step.
3. Install an RJ11/phone cord from the signal source to the phone port (labeled IN) on the surge protector.
4. Plug the device you want to protect from phone line surges into the OUT phone port on the surge protector.
5. Test to make sure that the device is working properly.

If you have followed these steps and the RJ11/phone connectors are still not passing a signal, the unit requires replacement.
