Global AC MCB Market Growth

The growing demand for AC MCBs can be attributed to the rapid development of infrastructure projects worldwide. In 2022, China, Brazil, Vietnam, India, and Indonesia accounted for 75% of the total private investments in infrastructure, which reached USD 68.3 billion. The East Asia and Pacific recorded a 17% increase in PPI (private participation in infrastructure), while Latin America and the Caribbean region witnessed a growth of 16%. In 2022, South Asia recorded an impressive PPI of USD 13.9 billion, which was the highest in a decade, and accounted for over 15% of all global commitments. This is expected to rise the AC MCB market value over the forecast period.

Moreover, the increasing development of smart houses worldwide is creating a favourable market outlook. There are around 175 million smart houses worldwide, with the United States, China, and Japan being its largest markets. By the end of 2024, around 555 million voice assistant devices are expected to reach smart homes, since they have emerged as their most appealing gadgets. By 2027, the Internet of Things (IoT) industry is expected to generate a high revenue, thereby leading to AC MCB market expansion. Smart devices are expected to become commonplace across such households, which is expected to result in market development.

Key Trends and Developments

Increasing electricity demand worldwide; rapid infrastructure development; increasing safety awareness; and rapid technological advancements are factors favouring the AC MCB market growth.

May 2023

The Energy Market Authority of Singapore mandated all private residences and Housing Board flats to install RCCBs (residual current circuit breakers) by July 1, 2025, otherwise USD 5,000 fine can be imposed on households.

February 2023

The burgeoning growth of the e-commerce industry in the UAE prompted Schneider Electric to introduce an online platform, the Schneider Electric Online Marketplace, to enable numerous industries to benefit from the increased availability of electrical devices. This also positively shaped the AC MCB market outlook.

June 2022

PFIFFNER Group, a leading Switzerland-based company engaged in manufacturing electricity transmission and distribution components, announced the development of a new high voltage AIS (air-insulated switchgear) circuit breaker for electricity distribution substations which uses an F-gas free and SF6-free as its insulation media, thereby reducing carbon emissions and ensuring safe operating standards for electrical grids. This also fuelled the AC MCB market development.

December 2020

Schneider Electric launched a new production line for premium low-voltage circuit breakers crucial for protecting power distribution networks in industrial and commercial buildings. This production line manufactures Molded-Case Circuit Breakers and Air-Cicuit Breakers with the label of "Made in the Kingdom of Saudi Arabia".

Increasing electricity demand worldwide

Strong economic activity, rising use of ACs amid intense heatwaves, and increasing adoption of heat pumps and EVs is expected to lead to a 4% surge in electricity demand, up from 2.5% in 2023. This can, in turn lead to AC MCB market expansion.

Rapid infrastructure development

The World Bank found that private sector participation for infrastructure development reached USD 91.7 billion in 2022, recording a year-on-year growth of 23%. This was especially true for low-and middle-income countries.

Increasing safety awareness

Consumers and businesses are becoming increasingly aware of the importance of electrical safety, which is boosting the adoption of reliable electrical safety devices, such as AC MCBs. This is driving the growth of AC MCB market revenue.

Technological advancements

The development of solid-state MCBs and electronic trip units promises to increase the market growth rate as they offer a high degree of precision and control for maintaining optimum current flow in circuits.

Global AC MCB Market Trends

Unlike electromechanical MCBs, new solid-state MCBs rely on electronic components such as integrated circuits and transistors for interrupting excessive current flow during power supply fluctuations. This ensures quicker response times, greater precision, and higher durability of AC MCBs. Moreover, as per the market analysis, the introduction of electronic trip units is expected to drive market growth, as they use microprocessors and sensors to establish control over electronic circuits to ensure their safety.
