The growth of commercial aircraft is majorly attributed to the rise in the number of domestic and international passengers, technological advancements, and the rise in the tourism sector.
By type, the thermal aircraft circuit breaker sub-segment dominated the market in 2021. The thermal circuit breaker is an electromagnetic component that trips the breaker when the current is too high. This kind of circuit breaker can instantly react to problems such as power surges as well as difficulties like improperly grounded electrical circuits.
The thermal aircraft circuit breaker is compact and lightweight that facilitates safer operations and provides high resistance to shock. These are predicted to be the major factors driving the aircraft circuit breakers market demand during the forecast period.
By system type, the AC sub-segment dominated the global aircraft circuit breakers market share in 2021. AC circuit breakers are more common than DC circuit breakers as they do not have a steady rate of voltage. The AC circuit breakers will disconnect themselves from the main power when excessive current is detected.
This offers protection to the wiring system in case of overheating. AC circuit breakers are widely deployed in aircraft as they can power high motor drives and are used for long-distance power transmission. Also, the AC circuit breakers have zero-crossing points in each cycle.
By voltage, the medium voltage sub-segment dominated the global aircraft circuit breakers market share in 2021. The growth of this sub-segment can be attributed to the wide range of commercial, industrial, and power plant settings where ACBs with medium voltage are used. Medium voltage circuit breakers operate at a voltage of 10KV to 35 KV, have an easy mechanism, are installation friendly, reliable, and safe. The medium voltage aircraft circuit breakers provide superior dielectric medium, have a high service life, require minimum maintenance, are compact, and cost-effective.
The low voltage sub-segment is the second most dominating sub-segment owing to an increase in the use of low voltage circuit breakers for managing power station auxiliaries, electricity sharing systems, and maintaining switchgear and interior medium voltage.
By region, North America accounted for the highest market share in 2021. This growth is majorly attributed to an increase in spending by the major U.S. firms including AMETEK, Inc., Amphenol Corporation, Astronicas Corporation, GE Aviation, and others. For instance, AMETEK, Inc., is the leading manufacturer of electronic and electromechanical devices for aircraft. Also, the U.S. has one of the largest aviation industries in the world owing to the presence of a large number of commercial and military aircraft. The commercial aviation sector accounts for more than 5% of the U.S. GDP which was equivalent to $1.25 trillion in 2022.
