The Right High Quality Power Surge Protector

High Quality, High Performance Power Surge ProtectorsHigh Quality High Performance 3 Phase SPDs

We provide High Quality Data-Line, Telecom-Line, Custom Design and Power Surge Protector equipment. Our devices are designed for the industrial, commercial, solar, wind, military and residential markets.

Surge Suppression, LLC transient voltage surge suppressor devices are not the average "off the shelf" mass-produced commodity type equipment. Our Advantage Series SPD designs do more for your electronics and electrical system than just mitigate standard impulse surges.

This is not just a marketing claim. It's a result of a determined, quality design approach to providing the best surge protector options available.

Below we detail our industry leading, Full Spectrum Protection design.

The Advantage Series power surge protector is... often imitated... but rarely duplicated...

High Quality Power Surge Protector Design

Optimal Responsive Circuitry

Defines SSI's overall SPD design approach in applying state of the art components with innovative, hybrid designs, custom circuit boards and patented fusing methodology. Combined to work together effectively, efficiently and reliably, Optimal Response CircuitryTM provides the best surge protector designs available today:

  • Discrete All Mode Protection
  • Voltage Responsive CircuitryTM
  • Frequency Responsive CircuitryTM
  • Patented Electrochemical Encapsulation

Discrete All Mode Protection

Our high performance SPDs employ a true Discrete All Mode Protection design. This design provides independent protection elements for all possible electrical pathways (modes) in a given electrical system.

Why This Design Provides Superior Protection:

  • There is no sharing of protection components to protect a pathway in our gear. If there is an electrical pathway in the system, we protect it with individual components. Unlike most other SPDs, we don't use a four mode or a seven mode protection design to protect ten. If there are ten modes, we protect all ten directly.

  • We don't skip protecting a pathway altogether claiming surges don't occur in that mode. Surges can occur in any mode. This has been proven in the field and can be found stated in electrical industry publications.

  • Voltage Equalization. By bonding all pathways (modes) to the same potential (our gear design) you create voltage equalization during a surge event. Our design mitigates power surges AND equalizes the voltage during a surge event.

  • Delivers industry best Let-Through Voltage (MLV) performance.

Voltage Responsive Circuitry

Designed to mitigate repetitive high-energy impulse transients generated by lightning, power system faults and load switching. This multi-level hybrid network design provides the brute strength and durability needed to handle repetitive high amplitude transients.

  • This technology is standard on all Surge Suppression, LLC units.
  • 20kA - 900kA Ratings

Frequency Responsive Circuitry ™

This technology can be added to our base VRCTM unit and is specifically designed to protect critical electronic circuits and microprocessors.

Provides electronics with Full Spectrum Protection

  • Frequency Responsive Circuitry ™ technology employs a multi-stage hybrid design blending SSI's Optimal Response Circuitry ™ with advanced Frequency Responsive Performance.

  • The resulting hybrid design suppresses internally generated RingWave transients down to harmless levels, yet is still capable of handling thousands of repetitive high-energy impulse surges. This combination provides a level of durability and performance that is unmatched.

  • Without Frequency Responsive Circuitry™ sensitive equipment is susceptible to repetitive damaging RingWave transients.

  • Do not confuse SSI's Frequency Responsive Circuitry™ technology with EMI/RFI Filtering or partial SineWave Tracking. EMI/RFI Filtering nor partial SineWave Tracking circuitry performs to the level of SSI's Frequency Responsive Circuitry™.

Electrochemical Circuit Encapsulation

All Surge Suppression, LLC power surge protector devices utilize high dielectric circuit encapsulation. This technology is widely used in high-end, mil-speck, industrial and commercial applications. The encapsulation enhances the Let-through voltage performance by reducing the overall size of the device. Durability and longevity is improved by increasing circuit integrity.

High Quality Options

Many SPD's in the marketplace are a one-size-fits-all type device. Essentially, the same device design is used when different types of protection technology or additional device options would provide better solutions.

Examples when different protection technologies are warranted...

  • Multiple Surge Type Environments
  • Installation Scenarios
  • Connection Methods
  • Fusing Applications 
  • kA Potentials

We provide quality options to address these different scenarios. This provides the best protection designs available.


Because of the commitment to provide a superior SPD that is built to last, SSI SPDs are supported with the finest warranty available. There are no outlandish claims made by our warranty. As such, there are no fine print "nuggets" or "grey areas" that many other product warranties contain. This warrant couldn't be supported if the SPDs didn't perform.

All high performance units are backed with a 10 Year or Industry Leading 25 Year "No Hassle" Warranty.  These Warranties include damage to our units caused by lightning strikes.
