Surge Protector Comparison
Plug-In Devices

A power surge protector comparison can be difficult... especially if you want to discuss product literature performance claims vs their actual effectiveness when put into use.

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?

Panel or Plug-In Protectors: Unit Design is Key

It doesn't matter if the SPD is a panel application unit for your business, a whole home unit for your house or the everyday outlet surge protector type.

Circuitry used, quality of components and type of components in the devices are important. Many times these components may be similar.

However, combining components, design and testing of the devices are 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.

Typical Protection Designs

Types of protection designs available in both Panel and Plug-In units:

  • Standard Clamp Circuitry
  • EMI/RFI Filters Circuitry
  • Frequency Responsive Circuitry... or Sinewave Tracking Circuitry
  • Series Mode/Coil Circuitry

Device's available may incorporate one or more of the circuitry types to improve effectiveness - but again, type, quality number 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 type 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.

Historical Comparison

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. The job was 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 were not the same.

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:

  • 6 Outlets
  • 3-Foot Cord
  • 120 Volt/15 Amp Circuits

Basic Unit Marketing Protection Spec's:

  • Unit 1: Surge Protector - No Spec

  • Unit 2: 585 Joules - 36,000 Amps Maximum Spike Current;  Includes EMI/RFI Filtration, All Mode Protection and down line Equipment Protection Warranty

  • Unit 3: Discrete All Mode Protection - 90,000 Amps Peak Surge Current; Includes Enhanced Sinewave Tracking, 25 Year "No Hassle" Warranty

All three units were sold as "electronics" protection gear.

  • The first unit was purchased from a "Big Box" electronic store.
  • The second was purchased from a "Computer Store".
  • The third unit was purchased from the manufacturer.

The equipment being protected:

  • Two PC's
  • Two Monitors
  • One Laser Printer
  • Three different Cable/DSL Routers (one at a time)

High Quality, High Performance Plug-In Surge Protectors

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, quality and quantity of components and types of components used in the device... all help determine the units overall effectiveness.

This is true for both plug-in units and TVSS panel surge protector units.

All surge protectors are not created equal. Although at times, marketing performance claims seem to take you in that direction.

Some product marketing materials are accurate and some are not so accurate. How the product works when in use is whats really important.

Remember... all three units were marketed as... electronics protection.
