The global molded case circuit breakers (MCCB) market size was valued at USD 6.23 billion in 2023 and is projected to reach USD 15.52 billion by 2030, expanding at a CAGR of 14.0% from 2024 to 2030. The surge in electricity generation and transmission investments is a major factor driving market growth.
Molded case circuit breakers are designed to safeguard electrical circuits from overload and short circuits by interrupting excessive current. Unlike standard circuit breakers, MCCBs have a higher interrupting capacity and can handle heavier loads, making them highly suitable for industrial and commercial applications.
The primary growth driver is the rise in global electricity generation. According to Enerdata, world power generation grew by 2.6% in 2023 on a year-on-year basis, maintaining steady growth above 2.5% between 2010 and 2019. Growth was particularly strong in BRICS nations, which contributed 45% of global power output. Notably, China, India, and Brazil recorded year-on-year increases of 6.9%, 6.9%, and 4.8%, respectively.
Expanding investments in data centers are creating strong opportunities for MCCBs. Data centers require robust power infrastructure for uninterrupted operations, where MCCBs play a crucial role in protecting against electrical faults. For instance, in April 2024, Google announced an investment of USD 3 billion to build and expand data center campuses in Virginia and Indiana.
However, high installation costs remain a major restraint. Factors such as higher ampere ratings, advanced features like ground fault protection and remote monitoring, robust design requirements, and labor expenses make MCCBs more expensive compared to conventional circuit breakers.
