MINIATURE CIRCUIT BREAKERS (MCB) MARKET KEY FINDINGS

GLOBAL CRISES IMPACTING MINIATURE CIRCUIT BREAKERS (MCB) MARKET

COVID-19 IMPACT

Miniature Circuit Breakers (MCB) Market Had a Negative Effect Due to Supply Chain Disruption During COVID-19 Pandemic

The global COVID-19 pandemic has been unprecedented and staggering, with the market experiencing lower-than-anticipated demand across all regions compared to pre-pandemic levels. The sudden market growth reflected by the rise in CAGR is attributable to the market’s growth and demand returning to pre-pandemic levels.

The outbreak of COVID-19 pandemic greatly affected the miniature circuit breakers (MCB) market share, especially in the first waves of 2020 and 2021. The international distress in the production and chain ware processes were the reasons why there were delays in their production, component scarcities, and logistical congestion in production. Both residential and commercial construction either stopped or got delayed during lockdowns and this sharply fell demand of electrical parts such as MCBs. In addition, most industries like automotive, property or manufacturing industries downsized their operations meaning less installation of electric systems or retrofitting of the systems. The pandemic also influenced the capital spendings in the infrastructure and power distribution pipelines, slowing down MCB adoption even further. Also, firms experienced insufficient labor, plant shutdowns, and limitations to site access that interfered with preservation and modification efforts that frequently spur the demand of MCB substitution. Although fundamental services like utilities or healthcare registered constant usage of MCB, the rest of the market did not flourish due to the global economic recession. Nevertheless, after 2021, the market started to recover slowly given that the governments responded by implementing stimulus plans, resuming infrastructural projects, and focusing on digitization and automatization. The recovery cycle has reverted the demand but the sustainable impact of supply chain challenges still remains an issue in changing the speed of normalization in the industry.

MARKET DYNAMICS

Market dynamics include driving and restraining factors, opportunities and challenges stating the market conditions. 

DRIVING FACTORS

Rapid Urbanization and Infrastructure Development Boost the Market

The soaring urbanization and infrastructural growth rate in most parts of the world is the biggest stimulus in the Miniature Circuit Breakers (MCB) market growth. Smart cities and residential and commercial houses are being developed in large quantities in the newly developing economies and they have the need of modern electrical safety systems. Electrification programs and energy availability programs are supported by governments which means that more solutions are needed in the area of circuit protection. MCBs, owing to their reliability, compactness, and ease of installation, tend to be used in new building works and upgrade of electrical systems. Also, the development of the markets in the industrialized countries that runs on energy-saving and safety regulation is also stimulating MCB demand. As smart buildings and green infrastructure become a reality, so is the demand of MCBs with intelligence monitor. The urban development which is closely related to the electricity demand, guarantees a market opportunity consistently to the manufacturers of MCBs in the projects undertaken by the government and the privately owned enterprises.

Growing Emphasis on Electrical Safety Standards and Regulations Expand the Market

The increase in the awareness levels regarding electrical safety as well as strict government legislation are playing a major role in enhancing the MCB market. Circuit protection devices are required in residential, commercial and industrial installations by regulatory bodies around the world to eliminate electrical hazard. In order to be compliant with the safety requirements like IEC 60898, UL 489 or BIS norms, it is necessary to employ quality MCBs. The insurance firms and inspection departments also need the strong protection devices to reduce the chances of the fire and damages of equipment. Consequently, the number of consumers using certified and dependable MCBs is escalating beyond frontier fuses or low quality items. Such installations are directly dependent on an industry like manufacturing and data centers where safety of the equipment and unbroken power source are at stake. Moreover, the pressure to ensure sustainability and energy efficiency provided by global institutions is also causing an impact on the product design and quality standards, which makes production with MCBs with compliance with the standards continuous.

RESTRAINING FACTOR

Price Sensitivity and Market Competition in Emerging Economies Potentially Impede Market Growth

The high price sensitivity of the consumers in the developing economies is one of the major inhibitors of the MCB market because customers tend to place more emphasis on cost than quality. Although there are premium MCBs of well-known brands available, that are safer and reliably tested, the existence of low-priced variants by other unorganized or local manufacturers bring the price-based intense competition with them. This will restrict the intrusion of high end technological oriented MCBs in cost sensitive markets. In other parts, it is possible to use the non-proper devices as the safety rules are not strictly followed, which creates safety issues and affects the general market development. Moreover, the increased cost of raw materials (such as copper and plastics) contributes to further straining of the manufacturers in keeping margins as competitive products. Consequently, firms require to maintain a balance between low prices and quality to ensure that business is maintained in such markets.

Rising Adoption of Renewable Energy Systems Create Opportunity for The Product in The Market

Opportunity

The move all over the world towards the use of renewable energy is a big opportunity to the MCB market. Any solar power, wind power or hybrid power plants installation must have a strong circuit protection to make sure that variable power loads are handled safely. Photovoltaic (PV) panels, inverters, battery storage systems and microgrid use MCBs to guard against overloads and short circuits. In view of the incentive and subsidies provided by the government of clean energy adoption, the utilization of rooftop solar systems and rural electrification schemes is also increasing. This growth brings about fresh demand of MCBs that are suitably modified to fit DC usage and rough outdoor settings. There is an opportunity to innovate by manufacturers and produce niche products specific to renewable sector. Expansion of off-grid and decentralized energy creation also creates an even greater opportunity to incorporate MCBs into a myriad application, both at a residential and at a utility scale.

Counterfeit and Substandard Products in the Market Could Be a Potential Challenge for Consumers

Challenge

This is indeed a major barrier in the MCB market the counterfeit and low-quality products that administer to creep into the market, particularly in the third world. These poor quality of MCBs are usually not properly certified, posing safety risks of fire outbreaks and failure of equipment. Availability of such products discredits the confidence of consumers and the established brand name. It also mis-distorts fair competition in the market since it provides substitutes, which are cheaper yet below par in performance. Distribution channels within the case of counterfeiting goods are not coherent and enforcement of regulatory measures at the country level is non-existent, which makes it difficult to identify and contain distribution of fake products. More so, insufficient information on consumers regarding the relevance of certified MCBs compounds the problem. The producers and the governments need to spend on education, quality inspection and digital tracking tools such as QR codes to check authenticity. It is important that regulations be strengthened and that regulators and industry players do collaborate to address this challenge and bring about safe electrical practices.
