Global Generator Circuit Breaker (GCB) Market Growth 2025-2031

The global Generator Circuit Breaker (GCB) market size is predicted to grow from US$ 1075 million in 2025 to US$ 1395 million in 2031; it is expected to grow at a CAGR of 4.4% from 2025 to 2031.

Generator Circuit Breaker (GCB) is an electrical device used to protect generators from electrical faults. It is designed to interrupt the flow of current in case of a fault or abnormal condition, thereby preventing damage to the generator and the connected electrical system.

For most utility companies, ensuring grid reliability, efficiency and security is a primary concern. As the power grid develops and load distribution changes, transmission and distribution networks are facing increasing pressure, making grid management more challenging. Globally, utility companies face many grid challenges and changing market conditions, including maximizing power plant availability, reliable plant operation, insufficient equipment service life, etc. After adopting generator circuit breakers, whether in the event of an operational failure or When the system oscillates or when a short-circuit fault occurs in the generator or transformer, the selectivity of protection will be improved, thereby improving the safety and reliability of unit operation.

Global key Generator Circuit Breaker (GCB) players cover ABB, Bharat Heavy Electricals Ltd., Eaton Corporation, and General Electric, etc. In terms of revenue, the global two largest companies occupied for a share nearly 44% in 2022.

At present, the development and application of generator circuit breakers at home and abroad are very rapid. They have developed from the original compressed air type to the SF6 type, and have been more widely used in thermal power plants, hydropower plants, nuclear power plants, pumped storage and other power plants. The technical level of generator circuit breakers continues to improve, the volume is getting smaller and smaller, the noise is reduced, while the rated current and breaking current are getting larger and larger, and the mechanical life of the generator circuit breaker is also increasing, with a high voltage of more than 10,000 times. It is much higher than the mechanical life of 3000 to 5000 times of ordinary high-voltage circuit breakers.

With the continuous improvement of development and manufacturing capabilities, the configuration and protection performance of generator circuit breakers have become more perfect, and the reliability has also been greatly improved. The continuous improvement of development and manufacturing capabilities has promoted the wider use of digital generator circuit breakers. The broad market prospects have also promoted the continuous improvement of the technical level of digital generator circuit breakers. The widespread use of digital generator circuit breakers has gradually become a trend.
