Medium Voltage Solutions
Heavy Industrial Solutions
Up To 7200 KV
SSI parallel connected medium voltage surge protective devices
(1 kVRMS to 7.2 kVRMS) protect mission critical system during
lightning strikes and transients that result from severe power
system faults. Our surge protective devices allow your critical
systems to stay up and running, keeping your electrical system
from suffering extensive damage, extended downtime and lost
revenue. This is critical to your company's well-being, bottom
line and future.
Custom and Specialty Products
Our engineering and manufacturing capabilities combined
with our experienced staff of professional design and
application engineers, affords us the ability to successfully
solve your most difficult surge protection applications. If
one of our thousands of standard models will not fit your
unique requirements, we will work hand-in-hand with your
personnel to make the necessary modifications and
design changes to provide you the most optimal
Telecommunications lines are very often the overlooked
"back door" for transients to enter your facility.
Telecommunication equipment often suffers the highest rate
of catastrophic damage of any system within a facility.
Protecting incoming telecommunications lines and lines
running from one building to another is not only prudent, it is
an NEC requirement.
Date communications lines and current loops are
the life blood of highly integrated systems and
networks, which are susceptible to failure from even
low-level transient activity, are often exposed to
high-level transients such as lightning. Protecting
these circuits is another key element of the
Optimal Protection Network.
Our Coaxial Surge Protectors are designed to effectively
address both high and low-level transient activity and
protect you from these costly interruptions. We offer a
number of different types of coax products which include
multiple connector types, grades of protection and multiple
Nearly every business today uses sophisticated and highly
integrated microprocessor based equipment and systems
that are increasingly prone to damage from even low-level
transient activity. The Dedicated Load Circuit Protection
models provide the level of protection needed to assure that
these mission critical systems survive and perform as
RV & Marine Surge Protectors
First Defense Surge Protectors by SSI offer the finest in
protection for your RV or Boat. We offer both hardwired and
pedestal protection for both 30 Amp and 50 Amp RV service.
Our products are designed for both surge and lightning
protection in mind with protection levels starting at 50 kA per phase.
