The global ac circuit breaker market is estimated to grow from USD 5.3 billion by 2028 from an estimated of USD 4.1 billion in 2023; it is expected to record a CAGR of 5.3% during the forecast period. Increased investment in industrial production is driving the demand of ac circuit breaker market.

“T&D Utilities: The largest- growing segment of the AC circuit breaker market”
Based on by application of AC circuit breaker , the industrial type segment is estimated to be the largest-growing market from 2023 to 2028. The increase in demand for electric power has led to increased investments in transmission and distribution infrastructures. The modern sub-station is the hub for data; therefore, filtering, analyzing, and responding to the data is critical. Hence, companies are now focusing on integrating solutions for smart utilities, which would enhance protection by decreasing energy losses due to the poor operational efficiency of traditional equipment. The use of sensors in AC circuit breakers helps in power quality measurements, fewer interruptions, the protection of secondary equipment, easy and safe maintenance, remote monitoring and control, and less use of highly valuable raw materials. T&D is the largest growing end-user segment in the global AC circuit breaker market due to the replacement of aging infrastructure in power utilities and the increasing electricity demand.

“Air-insulated: The third-largest segment by insulation type in AC circuit breaker market”
The air segment, by insulation type, is projected to hold the third-largest market size during the forecast period. An air AC circuit breaker is used to provide overcurrent and short circuit protection for electric circuits. Air AC circuit breakers are usually used in low- and medium-voltage applications. They are commonly deployed at places where the normal operating current ranges up to a few hundred amperes. When circuits working on such high currents are disconnected, an electric arc is formed between the disconnecting ends due to the air ionization around the terminals. This arc formation is harmful to the circuit as well as the terminals under operation. So, to extinguish this arc in minimum time, an arc quenching medium is required. In this case, the medium is air, which blows through the middle of the terminals quenching the arc.

“Very-high Voltage: The third-largest segment by type in AC circuit breaker market”
The air-insulated segment, by type, is projected to hold the second largest market size during the forecast period. The European air-insulated AC circuit breaker market is projected to grow from USD 554 million in 2022 to USD 726 million by 2028; it is expected to grow at a CAGR of 4.7% from 2023 to 2028.
Faulty tripping and switching operations of very high-voltage circuits are very rare; most times, these circuit breakers remain in ON condition and may be operated after long periods. The switchgear systems in this voltage range are also used in renewable power transmission and medium-voltage substations. The growing electrification and the integration of renewables in the national grid require rapid upgrade of transmission and distribution infrastructure. Automated and smart AC circuit breakers are used with smart grid technology to enhance efficiency. Hence, the demand for very high-voltage AC circuit breakers is expected to swell during the forecast period.

“North America: The second fastest and third largest-growing region in AC circuit breaker market”
North America is estimated to hold the third largest and second fastest market share in the AC circuit breaker market. North America is segmented into US, Canada, and Mexico. The AC circuit breaker market in North America has experienced consistent growth due to several contributing factors. One significant factor is the rising need for dependable and effective electrical distribution systems across residential, commercial, and industrial sectors. The demand for secure and reliable electrical infrastructure, combined with strict regulations and standards, has resulted in the widespread acceptance and utilization of circuit breakers. With the ongoing growth of the construction industry, fuelled by urbanization and population expansion, the demand for circuit breakers in residential applications is anticipated to increase. Similarly, the commercial and industrial sectors make substantial contributions to the circuit breaker market in North America. These sectors necessitate robust electrical systems to support diverse operations, including office buildings, retail spaces, manufacturing facilities, and data centres.
