Report Outlook

The global relay market size and share was valued at USD 9.56 billion in 2023 and is predicted to surpass at a CAGR of 6.20% during the forecast period.

The relay market is poised for growth, driven by several key factors, such as increasing power consumption, the surging popularity of electric vehicles, the adoption of smart power grids, and the increasing use of vehicular safety technology. Nonetheless, the market's expansion during the forecast period could face potential challenges due to fluctuating raw material prices. On a global scale, both emerging and developed nations are making substantial investments in the advancement of smart power grids, which is expected to boost the relay market in the years ahead significantly.

We use relays for a broad range of applications, such as cars and bikes (automobiles), home automation, test and measurement equipment, industrial applications, and many more. A fundamental electromechanical switch is known as a relay. Relays are buttons that connect or disconnect two circuits, simply like normal switches do when we manually open or close a circuit. However, a relay uses an electrical signal in the position of a manual process to manage an electromagnet, which then disconnects or connects another circuit.

Furthermore, the relay technique can be separated into two major classifications: no movable connections (MOS FET relay, solid state relay) and movable connections (mechanical relay). Also, the expanded demand for safer and more relaxed vehicles and rising sales of electric and hybrid vehicles are boosting the relay market demand.

Relay Market Size

Prominent relay manufacturers are currently grappling with formidable competition from unregulated market participants who offer inexpensive and subpar products. This category comprises local and grey market players. Local entities produce and sell goods under their in-house brand names, while the grey market involves the unauthorized import and distribution of products by dealers. These unorganized sector players outperform larger competitors due to their price competitiveness and well-established local supply networks, which are challenging for global companies to replicate. The expansion of relay sales in the grey market tarnishes the reputation of market leaders, as substandard products are sold under their branding. The growing sales of both local and grey market participants limit the opportunities for global players to boost their revenues and market share.

Industry Dynamics

Growth Drivers

Increasing capital allocation to renewable energy sources will Facilitate Market Growth

Globally, both developed and developing nations are shifting away from traditional fossil fuel-based electricity generation in favor of renewable energy sources. This transformation is, in part, a response to the growing concerns about climate change. The Intergovernmental Panel on Climate Change (IPCC) has identified the energy supply sector as the largest contributor to worldwide greenhouse gas emissions.

Renewable power generation technologies, often referred to as clean energy technologies, are increasingly being prioritized over conventional methods. Investments in these technologies are expected to rise worldwide, driven by the need to achieve electrification goals and address climate-related targets. According to projections by the International Renewable Energy Agency (IRENA), renewable energy has the potential to make up 57% of the global power supply by the year 2030.

By Type Analysis

The Thermal relays segment held the largest revenue share in 2022

Thermal relays serve as a safeguard against overloads in motors and various electrical equipment or circuits. Overloads occur when these machines or circuits operate abnormally, resulting in decreased motor speed, heightened current within the winding, and elevated winding temperatures. If the overload duration is brief, the current increase is modest, and the motor winding temperature remains within permissible limits, the overload is manageable. Thermal relays are capable of handling such overloads by design.

The Asia Pacific region is anticipated to emerge as the most extensive and swiftly expanding market for thermal relays.

By Voltage Range Analysis

The Medium voltage segment accounted for the highest market share during the forecast period

Medium voltage relays are protective devices designed for voltage ranges spanning from 1 kV to 33 kV. These relays typically serve in networks characterized by lower voltages and often share similar applications with high-voltage relays. Their primary deployment occurs within distribution utilities, where they play vital roles in safeguarding distribution transformers, feeders, busbars, and various electrical components. Moreover, these relays are integral to energy-intensive sectors such as mining, power generation, and oil gas.

Due to their extensive use in distribution infrastructure, this segment is poised for growth in both developing and developed regions across the globe, with the most significant markets situated in Asia Pacific, North America, and Europe. Key players in this sector include Schneider Electric, ABB, and AMETEK.

By Mounting Type Analysis

The DIN Rail segment accounted for the highest market share during the forecast period

DIN rail mounting is a versatile solution that allows multiple timers to be stacked on a single DIN rail, making it invaluable for various applications. DIN rail-mounted relays are widely used in commercial and cabinet timing and are particularly important for manufacturers of power distribution boards, industrial control cabinets, meter cabinets, and control panels. Additionally, DIN rails play a vital role in connecting various components to a single datalogger terminal, establishing power buses, and streamlining the installation of equipment like power supplies, conditioners, and breakers.

The key catalyst propelling the expansion of the DIN rail segment within the relay market is the surging demand for industrial equipment. As the global population steadily increases and urbanization remains a prevailing trend, the utilization of electrical components, including circuit breakers, fused terminal blocks, and wire connections, is on the upswing. Consequently, this heightened demand is poised to boost the need for DIN rail-mounted relays, with a particular emphasis on the Asia Pacific region.
