China's circuit breaker industry

In the past decade, China's circuit breaker industry has completed a paradigm shift from 'traditional protection devices' to 'intelligent power terminals' under the empowerment of 5G. On the technical level, the low latency characteristics of 5G enable millisecond level remote control. The intelligent circuit breaker integrates sensing, communication, and intelligent control technology, which can monitor parameters such as current, voltage, and power in real time. The accuracy of fault prediction has been significantly improved, and the product development cycle has been shortened by more than 40%. The market size continues to expand. The market size of intelligent circuit breakers is expected to reach about 12 billion yuan in 2025, and is expected to exceed 52 billion yuan in 2026. The market size of intelligent switchgear is expected to reach 132 billion yuan in 2024, and is expected to exceed 150 billion yuan in 2025. Strong application driven, emerging scenarios such as wind power, photovoltaics, charging piles, 5G base stations, and intelligent computing centers are driving high-performance demand. In 2026, solid-state circuit breakers will usher in the 'explosive year'. The policy environment is favorable, and the 'Action Plan for Stable Growth of Electronic Information Manufacturing Industry from 2025 to 2026' and the 'Dual Carbon' strategy are promoting the industry's transformation towards intelligence, modularity, energy conservation and environmental protection. Leading companies such as Liangxin have launched innovative products such as 2000V high voltage and 40KV medium voltage. Overall, 5G empowerment has enabled the circuit breaker industry to upgrade from 'single protection' to 'system integration', driven by both technological innovation and industrial upgrading, providing core support for new power systems and intelligent manufacturing.
