Distribution-class MOV arresters cluster tightly on core protection physics, but they separate on documentation quality, duty-class breadth, housing choice, creepage flexibility, and how explicitly public literature exposes TOV and energy behavior.
These families expose the cleanest public rating, protective-level, and physical tables.
These families sit at the top end of the normalized heavy-duty distribution energy-density band in this dataset.
These lines consistently plot near the bottom of the normalized 10 kA protective-level band for common 9-36 kV ratings.
Most competitors are polymer-only in this class; GE and Meidensha still preserve porcelain-backed paths in public literature.
These entries normalize to the broadest creepage customization emphasis, especially at 25 and 31 mm/kV.
In this first-pass normalized dataset, GE Vernova, Eaton / Cooper, and TE / Tridelta sit at the top end of the heavy-duty distribution energy band. Siemens remains very competitive, but its public brochure expresses energy very consistently at the catalog level rather than stretching to the widest normalized band.
Siemens, Hubbell, and Hitachi Energy appear strongest at keeping 10 kA protective levels low in common 9-36 kV distribution ratings. Hubbell especially stands out because public PDV tables make the tradeoff between normal-duty and heavy-duty classes very easy to read.
Most of the current market has moved decisively to polymer housings for distribution class. GE Vernova and Meidensha are the notable exceptions in this dataset, with public literature that still preserves porcelain options or porcelain-heavy lineages.
Siemens Energy and Hubbell are the clear leaders on public-data transparency. That matters for SurgeIQ because those vendors set the standard for how renderable, machine-readable comparison data should look.
