ST80-3P
80kA per phase surge protection device for downstream protection in industrial and commercial applications.
Product Overview
Description
The ST80-3P provides cost-effective surge protection for 3-phase electrical systems at distribution panels.
With 80kA surge current capacity per phase, this SPD protects against typical lightning strikes and switching transients.
The compact design is ideal for distribution panels and branch circuit protection.

FAE Expert Insights
"The ST80-3P is perfect for downstream protection in a coordinated surge protection scheme. Use it at distribution panels after a higher capacity SPD at the service entrance. The 80kA rating is sufficient for most distribution applications and the cost is lower than high-capacity units."

Frequently Asked Questions
Where should the ST80 be installed in a surge protection scheme?
The ST80 is designed for downstream protection in a coordinated scheme. Install it at: 1) Distribution panels; 2) Branch circuits; 3) After a higher capacity SPD (ST120 or ST200) at service entrance. This provides layered protection throughout the electrical system.
Use ST80 at distribution panels with ST120/ST200 at service entrance for coordinated protection.
