SOCOMEC is a French, family-owned industrial group specializing in low-voltage electrical power management, power switching, power conversion, energy monitoring, UPS systems, and energy storage. Founded in 1922 in Alsace, France, the company has grown from a small electrical-equipment manufacturer into an international group serving critical-power applications around the world. 1

Today, SOCOMEC positions itself around a central objective: making electrical energy safer, more available, more efficient, and more sustainable, particularly where interruption or poor-quality power can have serious consequences.

SOCOMEC’s current corporate information reports approximately 5,200 employees, €997 million in 2025 revenue, around 30 subsidiaries, and an international presence spanning all five continents. 2

At its simplest, SOCOMEC is a power-management and electrical-equipment company. Its products sit between the electrical utility/grid, electrical distribution system, industrial equipment, buildings, and critical loads. The company focuses on ensuring that electricity is:

• Available — power continues when the normal supply fails.
• Safe — people and electrical equipment are protected.
• Controlled — electrical circuits can be switched, isolated and transferred.
• Measured — electricity consumption and electrical parameters can be monitored.
• Efficient — energy losses and unnecessary consumption can be reduced.
• Stored — electrical energy can be stored and released when required.

This makes SOCOMEC particularly relevant to data centres, hospitals, industrial facilities, infrastructure, commercial buildings, energy facilities and other critical installations.

1922 — Foundation

SOCOMEC’s history begins on 22 April 1922 in Alsace, France. Its founder, Joseph Siat, was originally trained as a textile engineer. He established the Société des Ateliers de Construction Electromécaniques du Bas-Rhin. The company initially experimented with various electrical products before concentrating on equipment such as switches, circuit breakers and fuse-based protection systems. 3 This early specialization in electrical switching and protection would become one of SOCOMEC’s defining areas of expertise.

1945–1953 — Second generation

After World War II, Joseph Siat’s sons Pierre and Maurice Siat became involved in running the business. In 1953, the company adopted the shorter name SOCOMEC, under which it would subsequently develop internationally.

1980s — Internationalization

A major transformation occurred during the 1980s under Bernard Steyert, Joseph Siat’s grandson. SOCOMEC expanded beyond traditional switching equipment and developed capabilities in power electronics, energy conversion, electrical protection, power availability, and related technologies. This period marked the transformation from a primarily French electrical manufacturer into a more internationally oriented industrial group.

1990s — Measurement and monitoring

SOCOMEC subsequently expanded strongly into electrical measurement and power monitoring. One important development was the DIRIS range. SOCOMEC states that the first DIRIS network measurement analyser was launched in 1993, creating a foundation for its later energy-monitoring and energy-management business. 4

2010 — Fourth generation

In 2010, Ivan Steyert, the founder’s great-grandson, became the group’s leader. Under his leadership, SOCOMEC continued its international expansion while increasingly combining hardware with services, monitoring and connected technologies. The group also developed E’nergys, intended to complement SOCOMEC equipment with service and energy-performance capabilities.

2022 — 100th anniversary

SOCOMEC celebrated its centenary in 2022. The company used the anniversary to emphasize its evolution from a small Alsatian family enterprise into a global electrical-energy specialist while retaining its family ownership and independent structure.

SOCOMEC’s portfolio is much broader than simply UPS systems. Its major technology areas can be divided into several categories.

Power switching

This is SOCOMEC’s oldest and one of its most important areas. Products include equipment for electrical isolation, load breaking, switching, manual switching, motorized switching, automatic transfer switching, fuse-based protection, and specialized low-voltage switching applications. SOCOMEC offers switching equipment covering applications from approximately 16 A to 5,000 A, depending on the product family and application. These products are used in industrial electrical distribution, buildings, infrastructure and renewable-energy installations.

Typical applications involve using a SOCOMEC switch to isolate equipment, protect personnel, switch a circuit, and transfer a load to another source. This is particularly important when electrical continuity and maintenance safety are critical.

UPS and critical power

One of SOCOMEC’s most recognizable businesses is UPS (Uninterruptible Power Supply). A UPS protects critical electrical loads from problems with the incoming electrical supply. Depending on the system, this can include protection against power interruptions, voltage disturbances, electrical transients, frequency problems, and other power-quality issues. SOCOMEC provides UPS solutions for applications such as data centres, telecommunications, healthcare, industrial facilities, transportation, commercial buildings, and IT infrastructure. The purpose is not simply backup electricity; a modern UPS can be an important component of an overall power-quality and electrical-continuity architecture.

Automatic Transfer Switching

Another major SOCOMEC speciality is automatic source transfer. If the utility supply fails, a facility may have an alternative source such as a generator or second utility source. An automatic transfer system can detect the problem and transfer the load to the alternative source. This is particularly important for hospitals, data centres, airports, industrial plants, telecommunications, infrastructure, and emergency systems. SOCOMEC operates in a part of the electrical industry where continuity of supply is often more important than simply distributing electricity.

Electrical measurement and monitoring

SOCOMEC is also active in power measurement and energy monitoring. Its measurement technologies can monitor parameters such as voltage, current, active power, reactive power, apparent power, energy consumption, power factor, electrical quality, and other network characteristics. The DIRIS family is particularly associated with this area. The objective is to help organizations understand what is happening inside their electrical networks and identify opportunities for energy efficiency, fault detection, maintenance, capacity planning, and operational optimization.

Energy storage

Energy storage has become increasingly important to SOCOMEC’s business. Energy-storage systems can be used to store electricity, provide backup power, stabilize electrical networks, integrate renewable energy, reduce peak demand, improve energy flexibility, and support microgrid applications. SOCOMEC sits at an intersection between the traditional electrical-equipment industry and the modern energy-transition industry. Its portfolio now encompasses not only controlling electricity but also storing and managing it.

Power conversion

SOCOMEC describes power conversion as one of its core areas of expertise. This includes technologies designed to maintain the availability and quality of electrical power. The company’s power-conversion portfolio includes UPS systems, static transfer systems, power monitoring, energy-storage solutions, and associated services. SOCOMEC specifically identifies critical-power applications as an important area of expertise.

SOCOMEC primarily serves B2B and professional customers, rather than ordinary household consumers. Its major customer sectors include:

• Data centres: Servers cannot simply lose power. SOCOMEC participates in the electrical architecture through UPS systems, switching, transfer systems, monitoring, energy storage, power distribution, and energy-management technologies.
• Healthcare: Hospitals and medical facilities have extremely high requirements for power continuity and electrical safety. Critical applications include operating rooms, medical equipment, emergency systems, IT infrastructure, and life-safety systems.
• Industry: Factories depend on electrical power for production machinery, automation, control systems, motors, process equipment, and safety systems. Power interruption can cause production losses, equipment damage and significant downtime.
• Infrastructure: Equipment is used in transportation, telecommunications, public infrastructure, utilities, and other critical facilities.
• Commercial buildings: Large buildings require sophisticated electrical-management systems for power distribution, backup, energy monitoring, switching, and energy efficiency.

SOCOMEC specifically identifies industry, infrastructure, healthcare, data centres, energy and buildings among its important application areas.

SOCOMEC is not simply a component manufacturer. Its business is a combination of Products + Systems + Engineering + Services. For large projects like data centres, the scope involves electrical design, equipment selection, system integration, installation, commissioning, monitoring, preventive maintenance, technical support, replacement/upgrade, and energy optimization.

SOCOMEC has developed service capabilities around its equipment as well as its hardware portfolio. Its current materials report around 120,000 on-site interventions per year and nearly 400 experts involved in commissioning, technical audits, consultancy and maintenance.

Although SOCOMEC originated in France, it is now an international organization. The company reports approximately 30 subsidiaries, 12 production sites, products/services marketed in 80 countries, and more than 100 distributors. This means that SOCOMEC’s operating model combines centralized technological expertise and manufacturing with local subsidiaries, distributors and service organizations.

In Asia-Pacific, SOCOMEC’s regional operations serve markets where data centres, industrial facilities, commercial buildings, infrastructure and energy-transition projects are expanding. For Southeast Asia, SOCOMEC’s technologies are particularly relevant to rapidly developing markets involving data centres, manufacturing, industrial automation, renewable energy, commercial buildings, infrastructure, and critical facilities. The company’s presence in India dates back to 1990, initially through a partnership, followed by independent operations from 2006. 5

One of the characteristics that distinguishes SOCOMEC from many large electrical-equipment companies is that it remains family-owned and independent. The company describes independence as an important part of its corporate identity. Unlike a publicly traded conglomerate whose strategic direction is strongly influenced by public shareholders, SOCOMEC emphasizes long-term decision-making, family ownership, independence, continuity, investment in technology, and sustainable growth. The Steyert family has remained involved across multiple generations. Ivan Steyert, the founder’s great-grandson, is the current leader of the group.

Technology development is central to SOCOMEC’s strategy. The company states that it invests approximately 8% of turnover in R&D. Its research activities cover areas such as power electronics, UPS technology, electrical measurement, switching technology, energy storage, power quality, digital monitoring, energy management, and electrical-system optimization. SOCOMEC also reports approximately 3,500 m² of test platforms, describing them as among the leading independent power-testing laboratories in Europe.

Historically, SOCOMEC’s business was heavily associated with electrical switching and protection. Today, the company’s scope has expanded toward the broader energy transition. The modern electrical system is becoming more complex because of solar PV, battery storage, electric vehicles, distributed generation, microgrids, data centres, electrification, energy-price volatility, and increasing demand for energy efficiency. This creates a need not only to distribute electricity, but also to measure, control, convert, store, optimize, and protect. SOCOMEC describes itself as an innovative player in energy transition and renewable energy, alongside its traditional critical-power activities.

SOCOMEC identifies several fundamental principles behind its business. The company’s long-term identity is particularly associated with Independence, Innovation, and Responsibility. Its corporate communications also emphasize openness and commitment as part of its culture. The combination is important because SOCOMEC presents itself not simply as an equipment vendor, but as an independent technology manufacturer with a long-term industrial perspective.

SOCOMEC operates in several highly competitive markets. Depending on the product category, its competitors can include major international electrical and power-management companies such as Schneider Electric, Eaton, ABB, Siemens, Vertiv, Legrand, Mitsubishi Electric, and Delta Electronics.

However, SOCOMEC has a somewhat distinctive positioning. It is smaller and more specialized than the largest diversified electrical conglomerates, while covering several closely related areas of critical electrical infrastructure. Its major differentiators are generally:

1. Long history in low-voltage switching: SOCOMEC has been working in electrical switching since its foundation in 1922.
2. Critical-power specialization: UPS, transfer switching and power availability are important parts of its identity.
3. Measurement + power management: The company combines electrical equipment with monitoring and measurement.
4. Independent/family ownership: This supports a long-term strategic orientation.
5. Engineering and service: SOCOMEC combines products with technical services and system-level expertise.

A useful way to visualize the company is as follows:

• Power Switching: Switches, Transfer switches, Protection
• Power Conversion: UPS systems, STS, Power quality
• Monitoring: Power meters, Monitoring, Energy management
• Energy Storage: Batteries / BESS / storage

These components come together to form Critical Energy Systems used in Data Centres, Industry, Healthcare, Infrastructure, Buildings, and Energy sectors. These aren’t completely independent businesses; they work together as components of a larger critical electrical-energy architecture.

SOCOMEC operates in an area that is easy to overlook but fundamental to modern society: ensuring electrical stability. A modern hospital, factory, airport, bank, telecommunications network or data centre cannot tolerate uncontrolled power interruptions. SOCOMEC’s role is to help organizations control and maintain the electrical infrastructure on which their operations depend.

In simplified terms, the chain is: Grid → Switching → Protection → Conversion → Backup → Measurement → Storage → Optimization. SOCOMEC has technologies covering much of this chain.

Based on SOCOMEC’s latest corporate information available in 2026, the group reports approximately:

• €997 million revenue in 2025
• 5,200 employees
• 30 subsidiaries
• 12 production sites
• 80 countries where its products/services are marketed
• 30,000 customers
• 18,000 product references
• approximately 8% of turnover invested in R&D

These figures place SOCOMEC firmly in the category of a major international specialist manufacturer, although it remains considerably more focused than diversified giants such as Schneider Electric or Siemens.

SOCOMEC is essentially a specialist in making critical electrical power systems safer, more available, measurable, controllable and energy-efficient. It combines products with technical services and system-level expertise.
