The global molded case circuit breakers market size was estimated at USD 6.23 billion in 2023 and is estimated to grow at a CAGR of 14.0% from 2024 to 2030. Increasing investments in electricity generation and transmission is propelling market growth.
A molded-case circuit breaker (MCCB) protects the electrical circuit from excessive current, which can cause overload or short circuits. Compared to a circuit breaker, an MCCB possesses a higher interrupting capacity and can thus handle larger loads. This ability makes it more suitable for commercial and industrial applications. 16a mccb
Rising electricity generation worldwide is the major growth driver for the market. According to Enerdata, world power generation increased by 2.6% in 2023 on a year-on-year (y-o-y) basis, maintaining a consistent growth of over 2.5% during the 2010-2019 period. A major growth of 6% was witnessed in BRICS, holding a 45% share of world power generation. Countries including China, India, and Brazil registered a y-o-y growth of 6.9%, 6.9%, and 4.8%, respectively.
Further, rising investments in data centers are anticipated to provide expansion opportunities for MCCBs. Data centers require a secure and dependable power infrastructure, and MCCBs become essential in such cases as they help maintain a continuous flow of operations against mishaps like electrical failures. Thus, an increase in data centers is expected to aid demand for MCCBs. For instance, in April 2024, Google announced an investment of USD 3 billion for building or expanding data center campuses in Virginia and Indiana.
The market growth faces hindrances due to the high cost of installing MCCB. Factors such as high ampere, a requirement for robust components, additional features like ground fault protection and remote monitoring capabilities, brand value, and labor costs add to the overall price of circuit breakers. The MCCBs are designed for applications that need high ampere, which makes them more expensive compared to standard circuit breakers.
“Molded case held a revenue share of around 80% of the global market in 2023.”
Miniature circuit breakers (MCB) and MCCB work similarly. The MCCB, however, can prevent short circuits and electrical overloads against high currents, whereas the MCB is an automatic electrical switch that works around low-voltage circuits. In terms of current ratings, MCCBs range up to 1600 A, whereas MCBs go up to 125A.
MCCBs have high interrupting capacity for demanding applications and also have remote operation options, which are not present for MCBs. However, MCBs have a faster turnaround time and are used in residential, commercial, and light industrial applications, which have lower current requirements.
“75-250A held the largest revenue share of 48% in 2023.”
The 75-250A power range dominates the market due to its versatility and widespread use in commercial and industrial sectors. This range is essential for protecting against overloads and short circuits, vital in construction, manufacturing, and infrastructure. Its reliability and efficiency make it the top choice for engineers and facility managers.
On the other hand, the segment above 250A is essential for large industrial and infrastructure projects, requiring robust power management systems. With the expansion of industries and the rising demand for power, both of these segments are poised for steady growth. This growth is fueled by technological advancements and stricter safety and reliability standards. For instance, in 2023, Schneider Electric, a leading global player in MCCB market, announced the launch of its new Masterpact MTZ3 MCCB series. This strategic initiative is aimed at addressing the growing demand for high-performance, energy-efficient, and digitally enabled circuit breakers across various industries.
Residential is expected to register a CAGR of 14.3% over the forecast period.”
The residential segment holds the largest revenue share in the MCCB market, driven by the increasing emphasis on safety and energy efficiency in home electrical systems. As more households adopt advanced electrical appliances and smart home technologies, the demand for reliable circuit protection has surged. Furthermore, growing concerns over electrical fires and outages have led homeowners and builders to prioritize high-quality circuit breakers, further solidifying the residential sector's dominant position in the market.
In the power utilities end use segment, MCCB plays a crucial role in ensuring the stability and reliability of electrical distribution networks. As utility companies invest in upgrading infrastructure and integrating renewable energy sources, the demand for robust circuit protection solutions has escalated. These circuit breakers are essential for managing power loads and safeguarding against faults in utility-scale operations, driving significant growth within this sector as utilities strive to maintain service continuity and meet regulatory standards.
“China held nearly 60% revenue share of the overall Asia Pacific molded case circuit breakers market.”
North America molded case circuit breakers market is aided by the growth in renewable energy in the region. According to the U.S. Department of Energy, wind power is the fastest-growing and lowest-cost source of electricity in the country, as of August 2023. Wind energy held a 22% share of new electricity capacity installed in the country in 2022.
The molded case circuit breakers market of Asia Pacific dominated the industry, accounting for over 35.0% of the global market's revenue share in 2023. Growing electricity generation, data centers, and dependency on renewable energy in the region is aiding need for MCCBs in the region
China molded case circuit breakers market is expected to register lucrative growth amidst growing electricity generation. The country ranked first in terms of electricity generation in 2023, with 9,456 MW. Also, one of the country’s largest utilities commenced construction of a USD 3.9 billion project for electricity transmission across three provinces in March 2024.
The molded case circuit breakers market of Europe is driven by the growth in the electricity grid. For instance, in April 2024, the EU Commission launched an Action Plan for Grids to modernize the region’s electricity grid and prepare for renewables-based electrification of the energy system.
