DynaShield Applications
ALLTEC’s Protection Pyramid depends on DynaShield® products to support its comprehensive facility framework. 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.
