FAQ.

Who owns Eaton, and what is the relationship to Cooper Power Systems?

Eaton is an independent, publicly traded power-management company (NYSE: ETN).

Eaton acquired Cooper Industries in 2012, and Cooper Power Systems became Eaton's medium-voltage power-delivery brand.

Cooper Power Systems switchgear, transformers, voltage regulators, reclosers, capacitors, and arresters are now sold as part of Eaton's electrical portfolio.

What medium-voltage equipment does Hawk source from Eaton?

Hawk sources Eaton medium-voltage switchgear (metal-clad, metal-enclosed, and pad-mounted), distribution and power transformers, transmission & distribution apparatus from the Cooper Power Systems line — voltage regulators, reclosers, capacitors, and surge arresters — and Cooper Power series underground cable accessories: loadbreak and deadbreak separable connectors to IEEE 386 and insulated cable splices to IEEE 404.

What is Eaton doing to expand US medium-voltage production?

Eaton has invested more than $1.5 billion in manufacturing capacity since 2023, and is increasing US-made medium-voltage switchgear output to meet data-center demand.

Eaton announced roughly $340 million to expand US three-phase transformer production, including a new facility in Jonesville, South Carolina, with output expected to begin in 2027.

In August 2025, Eaton acquired Resilient Power Systems, adding solid-state transformer technology to its portfolio.

How is Eaton responding to data-center electrification demand?

Eaton tied its recent US manufacturing expansions in medium-voltage switchgear and three-phase transformers directly to data-center and grid demand.

Eaton MV switchgear, distribution and power transformers, and Cooper Power Systems apparatus are common picks for data-center electrical rooms and utility tie-ins.

What standards does Eaton MV equipment meet?

Eaton metal-clad switchgear is built to IEEE C37.20.2.

Eaton transformers are built to IEEE C57.12.00 (liquid-immersed general requirements).

Cooper Power Systems reclosers are built to IEEE C37.60, and step-voltage regulators to IEEE C57.15. Exact ratings and standards are confirmed per quote.
