Similarly, in the aerospace sector, the company supplies technologies for generating, distributing, converting, and controlling power while minimising weight and maximising safety.

The portfolio spans several major power domains:

• Electrical power
• Hydraulic power
• Mechanical power
• Aerospace power systems
• Vehicle and drivetrain technologies
• Electrified vehicle systems

Current strategy increasingly focuses on the convergence of electrical power, digital technology, and electrification.3

Foundation and Early Years

Eaton’s history began in 1911 when Joseph Oriel Eaton II and Viggo Torbensen established the Torbensen Gear and Axle Company in Bloomfield, New Jersey. The enterprise was founded upon Torbensen’s patented internal-gear truck axle. The business subsequently relocated to Cleveland, Ohio, where proximity to the expanding American automotive industry offered significant commercial advantages.

Expansion and Diversification

During its early decades, the company underwent several name and ownership changes. In 1919, Eaton and Torbensen formed the Eaton Axle Company. Eaton later reacquired the Torbensen Axle business, renaming it the Eaton Axle and Spring Company. Acquisitions became a primary strategy for growth, and by 1932, the entity had become the Eaton Manufacturing Company, reflecting a diversified operation beyond its original axle focus.

Throughout the mid-20th century, Eaton expanded into automotive components, transmissions, industrial equipment, electrical products, hydraulics, aerospace, and vehicle systems. This acquisition-driven diversification transformed the firm from an automotive component supplier into a diversified industrial technology company with expertise in electrical, hydraulic, and mechanical power management.

Acquisition of Cooper Industries

A pivotal moment in modern corporate history occurred in 2012 when Eaton acquired Cooper Industries for approximately US$11.46 billion in a cash-and-stock transaction. This deal significantly expanded the electrical business and resulted in the combined entity being incorporated in Ireland as Eaton Corporation plc.

Prior to this acquisition, Eaton was a diversified industrial company; afterwards, electrical power management became central to its identity, establishing it as a major competitor in circuit protection, electrical distribution, switchgear, power quality, industrial controls, lighting, and electrical infrastructure.

Modern Eaton has shifted its portfolio towards businesses benefiting from major structural trends.

Electrification and Digitalisation

The increasing electrification of vehicles, buildings, and industrial processes drives demand for electrical distribution, circuit protection, power conversion, energy management, grid infrastructure, EV charging, and electrical safety. Concurrently, modern electrical systems increasingly integrate software, sensors, communications, and automation. Eaton combines hardware, software, monitoring, and services to address this digitalisation.4

Data Centres and AI

The growth of cloud computing and artificial intelligence has created substantial demand for reliable power infrastructure. Eaton identifies data centres and AI as key growth markets, supplying UPS systems, power distribution, switchgear, circuit protection, power monitoring, and electrical infrastructure.4

In 2025, the Electrical Americas unit generated approximately US$13.28 billion in sales, while Electrical Global generated US$6.82 billion. Together, these represented roughly US$20.1 billion, or about three-quarters of total company sales.

Aerospace

This segment develops specialised systems for fuel, hydraulics, motion control, power management, and propulsion-related applications. Serving commercial, military, business aviation, and space markets, Eaton reported approximately US$4.25 billion in aerospace sales for 2025.

Mobility

Derived from Eaton’s historical strength in vehicle technology, this segment serves commercial vehicles, automotive applications, off-highway vehicles, drivetrain systems, and electrified vehicles. Historically known for heavy-duty drivetrain and transmission technologies, the company has expanded towards electrification. In 2026, the former Vehicle and eMobility segments were reorganised into Mobility.

eMobility

This area focuses on technologies for electric vehicles, high-voltage systems, power distribution, power conversion, and vehicle energy management. Eaton leverages its combined knowledge of vehicle systems and electrical power management to support the transition to electrified transportation.

Eaton operates primarily as a B2B industrial technology brand. Major product categories include:

• Electrical protection: Circuit breakers and protection devices that safeguard equipment and personnel from electrical faults.
• UPS systems: Uninterruptible Power Supply systems providing backup and conditioned power for critical infrastructure such as data centres, hospitals, telecommunications, and financial institutions.
• Switchgear: Equipment that controls, protects, and isolates electrical apparatus, serving as fundamental infrastructure for power distribution.
