Best circuit protection is the one that’s “good enough”
Often times it’s not known what’s “good enough” as installations and locations will differ
Consideration of the technology is important as activation time (or peak voltages needed to turn on) needs to be considered
For example, a gas tube may not turn on until it reaches 300V +/- 20%
Upfront cost is typically a concern, but often cost of ownership isn’t taken into consideration
Some RF SPDs degrade with each surge (stand alone gas tube)
Results in replacement of product which often includes a roll-out to the site as well as cost of equipment damaged
Filters or hybrid RF SPDs are more costly, but typically don’t degrade with surge events
