Power quality · preliminary application guide
Define the installation, exposure, electrical system and environment. The selector translates Eaton’s supplied Surge 101 and Surge 102 guidance into a clear starting specification.
Preliminary selection
The result will show an application kA range, enclosure, electrical configuration and Eaton product-family starting points.
Each inch of conductor can add approximately 15–25 V to the let-through voltage. Use the shortest practical connection and twist conductors together.
Layer service-entrance, distribution and point-of-use protection. A downstream panel with upstream protection generally needs a lower kA range.
High-leg delta and HRG systems need special attention. An HRG wye system is treated as delta for SPD selection in the supplied training guidance.

This tool is a planning aid—not a final design, code determination, short-circuit study or catalog-number selector. Confirm voltage configuration, available fault current, upstream coordination and current Eaton product data with Collins Sales/Eaton before ordering. Current Eaton surge protection information ↗
