FAE Expert Insights
"The ST200-3P is our highest capacity surge protector for the most demanding applications. I recommend this for service entrance protection in high lightning areas and critical facilities. The 200kA rating provides maximum protection against direct lightning strikes. It's more expensive than lower capacity units, but the protection is unmatched."

Frequently Asked Questions
When should I use the ST200 instead of ST120?
Use ST200 for: 1) Service entrance protection; 2) High lightning exposure areas (coastal, mountain); 3) Critical facilities where downtime is unacceptable; 4) Areas with frequent thunderstorms. The extra capacity provides better protection against severe events.
Use ST200 for service entrance and high-exposure. Use ST120 for standard applications.
