A true power surge protector comparison can be difficult...that is...if you really want to discuss product literature performance claims.
Performance claims can be tough to verify - especially if you don't have a surge generator to actually "test" the device via test protocols to validate it's marketing claims.
After all, the performance claims are usually why you buy one product over another isn't it? And when it comes down to it...don't you want to make sure your purchase performs as advertised?
Otherwise, why buy it?
It doesn't matter if the SPD/TVSS in question is a panel type unit for your business, a whole home unit for your house or the everyday outlet surge protector.
Circuitry used, quality and type of components in the device are important. Many times these components may be similar.
However, combining the components and how they are used in the unit design is typically the point of quality separation.
Depending on how effective and dependable a protection unit you want...you have different choices of "design" and components available.
Types of protection designs available in both Panel and Plug-In units:
Device's available may incorporate one or more of the circuitry types to improve effectiveness - but again, type and quality of components and design are key.
Depending on unit design and other factors, performance and/or results will very with different units - again, regardless if the units in question are panel mounted TVSS or plug-in units.
Below is a simple example of three different outlet surge protector units that were used to protect the power side of a general home network. All three units use similar concepts and similar components to achieve protection.
Please Note: The surge protector comparison is provided to demonstrate differences in SPD equipment designs, their marketing claims and unit performance through a very basic test...
In the field usage.
This comparison is called "historical" because this is the result of three different units used over a 5 year time span to do the same job - to protect the power side of home network electronics.
The units in this surge protector comparison use some of the same components and have similar protection claims - however, the results are similar in two of three cases. In two of the three cases a protected piece of equipment failed.
All three units have similar capacity design spec's:
Basic Unit Marketing Protection Spec's:
All three units were sold as "electronics" protection gear.
The equipment being protected during this time:
Please remember; Depending on how effective and dependable a protection unit you desire - you have different choices of design and components available.
Depending on the quality of design and components of the device you choose also determines the units overall effectiveness.
This is true for plug-in and TVSS panel surge protector units.
All surge protectors are not created equal. Although at times marketing material performance claims seem to take you in that direction.
Some product marketing materials are accurate and some are not so accurate - especially when placed into actual use.
We learned this the expensive way. Thus our plug-in power surge protector comparison example.
Please remember, all three of these units were marketed for electronics protection.
