Technology Segment Analysis: Type 1 (Largest Segment) vs Type 2 (Fastest-Growing Segment)

Holding the largest share of the plug-in commercial surge protection devices market, the type 1 segment accounted for 53% in 2026. Its leading position is supported by its widespread deployment at service entrances, where it provides primary protection against high-energy surges caused by lightning strikes and external electrical disturbances. Commercial facilities increasingly rely on type 1 surge protection devices to safeguard critical electrical infrastructure, reduce equipment damage, and enhance overall power system reliability.

The type 2 segment is expected to witness the fastest growth as commercial buildings continue to expand the use of sensitive electronic equipment, automation systems, and digital infrastructure. Installed at distribution panels, type 2 devices provide effective protection against internally generated transient surges and residual overvoltages. Increasing investments in smart buildings and modern electrical systems are expected to accelerate adoption within this segment.

Power Rating Segment Analysis: > 150 kA (Largest & Fastest-Growing Segment)

The plug-in commercial surge protection devices market was led by the above 150 ka power rating segment, which accounted for 32.18% of the market share in 2026, while also emerging as the fastest-growing category. Its strong position is driven by the increasing need to protect mission-critical electrical equipment in commercial facilities exposed to high-energy surge events. High-capacity surge protection devices are widely adopted in data centers, industrial buildings, healthcare facilities, and large commercial complexes where uninterrupted operations and equipment reliability are essential. Growing investments in resilient electrical infrastructure and advanced power protection solutions are expected to further reinforce demand for the above 150 ka segment.
