Surge Suppression

DynaShield® Surge Suppression & Protection Devices

When clean, uninterrupted power is crucial, ALLTEC’s next generation surge protection devices are ready to provide the highest level of performance for the safety and reliability of your electrical systems.

Our surge protection devices incorporate many industry leading components including patented thermally protected MOV technology, some of the most advanced filtering, extremely reliable monitoring, and a commitment to supply the safest SPDs.

Electrical disturbances will occur. You must ensure the lifespan of your expensive electrical equipment is not compromised by protecting it with the best SPDs on the market. ALLTEC’s DynaShield surge protection devices provide superior protection and support for a wide variety of applications.

A power quality system is not complete unless it includes strike termination devices, surge protection devices, and a grounding system. ALLTEC’s Protection Pyramid depends on DynaShield surge protection products to fill this space in its comprehensive facility approach. Contact an ALLTEC solutions expert today to see which surge protection device fits your application best.

Surge Suppression

The second tier of protection diminishes the significance of random high-energy, short-duration electrical power transients through properly installed surge protective devices. These occurrences are typically caused by atmospheric phenomena (such as lightning strikes), utility switching, inductive loads, and internally generated overvoltages.

You can view typical installation locations in the application maps to the right by locating the numbers 5 and 6.
