The hard-wired segment accounted for the largest revenue share of 65.20% in the surge protection devices market share in 2024.

• Hard-wired SPDs are installed within the electrical system of a building, mostly at the service panel. The devices protect all connected appliances and electronics from power surges by diverting the excess voltage to the ground before it reaches sensitive equipment.
• Hard-wired SPDs are designed to handle larger voltage surges compared to standard plug-in units, providing better protection against severe electrical events.
• For instance, CITEL offers hard-wired AC surge protector in its product offerings. The products are designed for single and three phase AC networks connected to sensitive equipment.
• Therefore, the wide applications of hard-wired SPDs are propelling the surge protection devices market

The plug-in segment is expected to register the fastest CAGR during the forecast period.

• The plug-in SPD is used by plugging it into a wall outlet and then plugging electronic devices into the surge protector outlets.
• They provide protection against voltage spikes caused by factors like power grid fluctuations, lightning strikes, or powering on of large appliances.
• For instance, SolarEdge offers SPD plug-in in its product portfolio. The device is suitable for both new and existing installations.
• Thus, according to surge protection devices market analysis, the aforementioned factors are driving the market growth during the forecast period.

By Standard:

Based on the standard, the market is segmented into type 1, type 2, type 3, and others.

Trends in the Standard:

• Rising trend in adoption of type 1 SPDs to protect electrical installations from direct lightning strikes and to handle high voltage surges, in turn, drives the surge protection devices market size.
• Increasing adoption of type 3 SPDs to provide direct protection to sensitive electronic equipment, including computers, TVs, and audio systems.

The type 2 segment accounted for the largest revenue in the surge protection devices market share in 2024 and it is also expected to register the fastest CAGR growth during the forecast period.

• The type 2 SPDs are used to protect electrical equipment within a building's sub-distribution panels. The devices offer protection against residual surges from lightning strikes and internal switching in systems.
• These SPDs are the second stage of surge protection after a Type 1 SPD at the service entrance panel. Type 2 devices are installed on the load side of the main distribution panel to protect connected appliances and sensitive electronics. 
• For instance, Phoenix Contact offers Type 2 SPDs in its product portfolio. These devices are available in various elements including arresters, protection plugs, and others.
• Therefore, the wide applications of type 2 SPDs are driving the surge protection devices market

By Discharge Current:

Based on the discharge current, the market is segmented into less than 50 KA, 51 KA to 200 KA, and above 200 KA.

Trends in the Discharge Current:

• Rising demand in adoption of SPDs with discharge current less than 50 KA for use in home electrical panels and smaller office buildings.
• Increasing trend in adoption of SPDs with discharge current above 200 KA in main electrical panel at the service entrance to handle the initial surge from a lightning strike in large commercial or industrial buildings.

The 51 KA to 200 KA segment accounted for the largest revenue share in the market in 2024 and it is also expected to register fastest CAGR growth during the forecast period.

• The 51 KA to 200 KA discharge capacity SPDs are used in commercial and industrial places.
• These devices are used in applications where large surges of electrical current are expected, including the main power entrance of a building, industrial facilities, or locations prone to frequent lightning strikes.
• These devices handle a very high discharge capacity of 51 to 200 KA without damage and provide protection against large voltage surges.
• For instance, ABB provides ABB 4 phase industrial surge protector in its product offerings. The device is able to tackle 100 KA of surge current.
• Therefore, the market analysis depicts that the aforementioned factors are driving the surge protection devices market

By Application:

Based on the application, the market is segmented into industrial, commercial, and residential.

Trends in the Application:

• Rising adoption of SPDs in residential sector due to the need to protect sensitive electronics equipment from sudden power surges and spikes.
• Increasing demand of SPDs in industries including oil and gas, manufacturing, and others to protect equipments against over-voltages.

The industrial segment accounted for the largest revenue share in the market in 2024.

• In industrial segment, the SPDs are used to protect sensitive electrical equipment including machinery, control systems, safety interlock circuits, and communication systems from damage caused by sudden voltage spikes. The devices minimize downtime by diverting excess voltage to the ground.
• Industrial SPDs are suitable for high-power industrial applications as they are designed to handle large surge voltages compared to standard household surge protectors.
• For instance, DEHN SE offers various surge protection equipment for industrial buildings in its product portfolio. These devices can be energy-coordinated to ensure interaction of the distinct protection levels.
• Therefore, the market analysis shows that the wide applications of SPDs in industrial sector are boosting the surge protection devices market

The commercial segment is expected to register the fastest CAGR growth during the forecast period.

• In commercial segment, the SPDs are used to protect equipment such as computers, telecommunications systems, servers, and building management systems from sudden spikes caused due to lightning strikes, power fluctuations, or equipment malfunctions.
• Moreover, surge protectors provide multi-tier protection, including voltage spike protection on power lines, data lines, and other telecommunications lines.
• For instance, Siemens offers commercial SPDs in its product offerings. These products are available in BSPD, TPS4, and FSPD product ranges.
• Thus, the market analysis depicts that the rising utilization of SPDs in commercial sector is expected to drive the surge protection devices market demand during the forecast period.
