Issue:
How to choose the correct SPD?
Product Line:
Surge Protection Devices
Answer:
Choosing the appropriate Surge Rating for an SPD comes down to two things:
1) The location of the SPD within the electrical distribution, and;
2) The location of the facility (environmental surroundings)
Schneider Electric recommends the following surge current ratings based on SPD location within the electrical distribution.
Service Entrance Locations 240 kA
Distribution Locations 120-160 kA
Branch Locations 50-120 kA
