Molded Case Circuit Breakers Market

Molded Case Circuit Breakers Market: Type, Rated Current, End Use, and Region

Market Synopsis

The global Molded Case Circuit Breakers Market is valued at USD 8.95 Billion in 2024 and is projected to reach a value of USD 21.72 Billion by 2035 at a CAGR (Compound Annual Growth Rate) of 8.40% between 2025 and 2035.

Molded Case Circuit Breakers (MCCB) or molded case welder circuit breaker, as the name suggests, is a type of circuit breaker that has a body and electrical contacts made of molded plastic. This design offers many advantages over traditional mechanisms: it makes the MCCBs smaller and lighter than other types, which allows them to be located in places where other types could not go; they are also much more resistant to dust, water and oil than standard breakers as well as having higher short-circuit breaking capacity.

Long Life, Simple Design, and Lightweight to Drive Growth of Molded Case Circuit Breakers Market

The structure of molded case circuit breaker is very excellent, which makes it have high breaking capacity and long-life span, so it has many advantages such as large breaking capacity, good performance, small size and light weight etc. Which is superior to other traditional types of electric equipment. Compared with other kinds of electric equipment with similar use, the number of parts needed in mold made electric equipment is fewer than them, and the cost is low. Which greatly reduces the fabrication difficulty, maintenance difficulty and so on, which is more economical. The molded case circuit breaker is made by die-casting, so it has small sizes, light weight, high intensity, ensuring the installation can be completed in a short time without affecting the existing equipment. Therefor it is very suitable for power distribution system to replace fuses.

Market Segmentation

Global Molded Case Circuit Breakers market is segmented by type (molded case and miniature), rated current (0-20a, 21-75a, 76-250a, 251-800a, Above 800a), end-use (T&D, manufacturing & process, infrastructure, power generation, transportation), and region.

By Application, Power Generation Segment to Witness Lucrative Growth

Molded Case Circuit Breakers are increasingly being used in power generation facilities for new construction and current upgrades. This is due to their compact size, high breaking capacity, high short-circuit ratings, robust design, consistent performance, etc. A majority of the generators have either already upgraded or plan to upgrade with Molded Case Circuit Breakers.

Asia Pacific to Lead Global Molded Case Circuit Breakers Market

A new generation of Molded Case Circuit Breakers for the utility-scale generators is expected drive the Asia Pacific market around 2025-2035, which will be a key growth driver for the global market in the long run. In addition, stringent environmental norms aimed at reducing greenhouse gas emissions from power plants have been leading to stricter installation of emission control systems such as desulfurization, selective catalytic reduction (SCR), low NOx burners, etc in the region. This has led to increased demand of Molded Case Circuit Breakers for generator protection against overloads and short circuits due to rejection/unloading operations.

As a result, generators in Asia Pacific region will have a significant growth opportunity with a volume of more than 300.0 million units by 2024-2025. In addition, an increased number of generator installations from the recent past is expected to fuel demand for Molded Case Circuit Breakers, especially those using the latest technological developments such as Electronic Trip Units (ETU) and alternatives to electro-mechanically operated plunger mechanisms. Together, these factors are going to propel the demand for Molded Case Circuit Breakers in Asia Pacific region over next 10 years.
