Buying Guide

What is a difference between a surge suppressor and a power strip?

The surge suppressor devices come with room to connect two appliances only. On the other hand, you can connect more than two appliances with your power strip. It is common misconceptions that power strips and surge suppressors are the same things.

How much surge current capacity should I consider?

It depends upon the amount of protection you need to provide to your electronic equipment. However, please bear in mind that the optimal surge capacity is not an accurate science and no one can scientifically estimate it with the help of a standard algorithm.

What are Type 1, Type 2 and Type 3 surge suppressors?

Type 1 surge suppressors are the first line of defense against the surges from the grids, and for this, the power company has to be involved in the installation process of the device. Type 2 surge suppressors are fitted on the branch panels or the breaker panels. It is also known as the panel protector. Type 3 surge suppressors are the surge strips or the backups for the batteries. This device comes in handy at the point of use.

Why don’t surge suppressors last longer?

These devices are designed to take the hit from the energy burst and during the process protect the appliances and equipment in the home. If the surge protector is working fine, it means that there has been no energy spike of any kind. Otherwise, it would have taken the hit. It all depends on the time that has passed between the two waves, nothing else.

What is meant by clamping voltage of a surge suppressor?

The clamping voltage symbolizes better protection against the surge. However, it also limits the life expectancy of the device and the overall safety system as well. According to the UL rating, the lowest levels of protection are 330V, 400V, and 500V while the standard allowed voltage for 120V capacity suppressors is 330V.


After the analysis, the Isobar Surge Suppressor from Tripp Lite stood out. It is not only a top quality product but is also very convenient.
