Low Voltage Components Market (2026-2036)

The growth of this market is mainly driven by the rapid construction of data centers, the electrification of buildings, transport, and industry, rising investment in power grids and renewable energy, and the expansion of industrial automation. In addition, the growth of solar, battery storage, and electric vehicle (EV) charging, which require DC protection, the adoption of smart and connected circuit protection devices, stricter electrical safety codes, and the development of solid-state circuit breakers are further supporting the growth of this market.

The Low Voltage Components Market, also referred to as the low voltage electrical products, LV protection and control devices, or low voltage switching and protection market, comprises the devices used to protect, switch, control, and distribute electrical power in circuits up to 1,000 V AC and 1,500 V DC. The market includes circuit breakers, such as miniature circuit breakers (MCBs), molded case circuit breakers (MCCBs), and air circuit breakers (ACBs); residual current devices (RCDs), including residual current circuit breakers (RCCBs), residual current breakers with overcurrent protection (RCBOs), and arc fault detection devices (AFDDs); contactors and motor starters; overload and motor protection relays; control and protection relays; switches, disconnectors, and switch-fuses; fuses and fuse holders; surge protection devices (SPDs); and automatic transfer switches. These components are used in switchboards, panelboards, motor control centers, distribution boards, and machines. The market excludes assembled switchgear and panels. The market ecosystem extends from raw material and component suppliers to component manufacturers, distributors, panel builders and OEMs, electrical contractors, and end users.

Low voltage components are present in virtually every building, factory, data center, and infrastructure facility. They protect people and equipment from overloads, short circuits, earth faults, arcs, and surges, and control motors and other loads. As electricity becomes the main energy source for buildings, transport, and industry, the number of low voltage circuits and the demand for protection and control devices are increasing.

Electricity investment is rising rapidly. According to the International Energy Agency (IEA), investment in electricity supply and infrastructure is expected to reach nearly USD 1.6 trillion in 2026, or up to USD 2 trillion including end-use electrification, with power grid investment approaching USD 550 billion, up nearly 20% year on year. Investment in grids, renewable energy, battery storage, and end-use electrification all require low voltage components, from distribution boards and inverters to EV chargers and heat pumps.

Data centers are the fastest-growing source of demand. According to the IEA, global data centre electricity demand grew 17% in 2025 to around 485 TWh and is projected to roughly double to around 950 TWh by 2030. Data centers use large numbers of air circuit breakers, molded case circuit breakers, automatic transfer switches, and surge protection devices in their power distribution systems, and the growth of AI data centers with higher power densities is increasing the content of low voltage components per megawatt.

Leading electrical suppliers are reporting strong growth. Schneider Electric reported record 2025 revenue of EUR 40.2 billion, with organic growth of 8.9%, triple-digit order growth from data centers in Q4 2025, and guidance for organic revenue growth of 7% to 10% in 2026. ABB reported 2025 Electrification orders of USD 18,757 million, up 14%, and revenues of USD 17,357 million, up 12%, with data centers recording very strong double-digit growth in Q4 2025, including several large orders of more than USD 100 million each. Eaton reported 2025 sales of USD 27.4 billion, up 10%, with Electrical Americas sales of USD 13,276 million, up about 16%, and electrical sector backlog up 29% year over year at the end of December 2025, and guided to organic growth of 7% to 9% in 2026.

Electrification of transport and buildings is adding demand. According to the IEA, global electric car sales exceeded 20 million in 2025, accounting for about one-quarter of new cars sold. Each EV charger requires circuit breakers, RCDs, and surge protection, often including DC protection, and the electrification of heating with heat pumps, the growth of rooftop solar, and home battery storage are increasing the number of protection devices in homes and commercial buildings.

Industrial automation continues to support demand. Contactors, motor starters, overload relays, control relays, and switches are used to control motors, pumps, fans, and conveyors in factories, and investment in automation, semiconductor and battery plants, and process industries supports demand for these components. ABB reported that buildings improved in Europe and the U.S. in Q4 2025, offsetting weakness in China, and that utilities remained strong.

Technology is changing the market. Smart and connected circuit breakers with built-in metering and communication allow energy monitoring and remote control, AFDDs detect dangerous arcs that conventional devices cannot, and solid-state circuit breakers, which use power semiconductors instead of mechanical contacts, offer very fast protection for DC systems, data centers, and EV applications. Electrical safety codes and standards are also requiring more advanced protection in many countries.

Supply chains for low voltage components depend on copper, silver, steel, and engineering plastics, and on electronic components for smart devices. Manufacturers are expanding capacity to meet demand, particularly in North America, where data center construction has extended lead times for some electrical equipment, as reflected in the 31% increase in the Electrical Americas backlog of Eaton at the end of 2025.

The market is served through several channels. Large global suppliers, such as Schneider Electric, ABB, Siemens, Eaton, and Legrand, sell complete portfolios of circuit breakers, RCDs, contactors, relays, and switches through electrical distributors, panel builders, OEMs, and direct project sales; regional manufacturers, such as Chint, LS Electric, Fuji Electric, Hager, and Havells, have strong positions in their home markets; and specialists, such as Littelfuse and Phoenix Contact, focus on fuses, surge protection, and connection technology. Distribution networks and relationships with panel builders and electrical contractors are key to market access.

The value of low voltage components per installation is increasing. Data centers with higher rack power densities require larger and more numerous breakers and transfer switches per megawatt, electrified homes with EV chargers, heat pumps, and solar require more protection circuits, and safety codes are requiring AFDDs and RCDs in more circuits. Smart devices with metering and communication also have higher prices than conventional devices. As a result, market value is expected to grow faster than construction activity over the forecast period.
