ABB launches new circuit breaker solution for next-generation wind turbines

ABB is introducing a complete switchgear solution for wind turbines to support the deployment of larger wind turbines with higher yields. The solution offers the industry’s highest power rating for a complete switchgear solution, integrating a 7200A Emax 2 air circuit breaker and a 3200A AF Contactor, to provide outstanding reliability and switching efficiency.

To achieve better grid stability and higher yields, wind turbines are becoming more powerful. By 2030, onshore wind turbines will reach outputs of 8-10 MW, while offshore turbines will exceed 20MW. They are also becoming physically bigger with heights of more than 200 meters – roughly the same size as the Eiffel Tower.

Linda Wennberg, Head of Sustainable Energy, ABB Electrification, said, “ABB innovation is making sure big investments in the energy transition pay off. Our teams work closely with leading wind turbine manufacturers to identify innovation opportunities that help them run leaner and cleaner. Reliable clean energy is fundamental for a net zero future and this latest advancement provides a high reliability electrical switchgear solution with advanced fault protection and efficient high-power switching that will help customers avoid high maintenance costs and maximize yield.”



ABB is the largest manufacturer of components, systems, and services for onshore and offshore wind turbines worldwide. ABB provides converters, generators, electrical panels, low-voltage products and wind farm substations. Produced in Mission To Zero facilities, ABB’s Emax 2 air circuit breaker is a technology leader in energy transition applications and is part of the company’s EcoSolutions program, providing complete transparency on the environmental impacts of the complete product lifecycle.

Marzio Zambetti, Wind & Solar OEM Manager, ABB Electrification, said, “Next-generation wind turbines need next-generation electrical solutions. ABB is working with existing customers and with manufacturers developing new strategic supply chain collaborations, sharing our expertise in low-voltage technologies to give wind energy every opportunity to realise its full potential. As turbine sizes and outputs continue to grow, ABB is making it easier to build in higher safety, reliability and efficiency.”

Demand for wind energy continues grow. Forecasts expect global cumulative capacity to double from approximately 1.1 TW in 2024 to more than 2 TW in 2030. Source: Wind Market Outlook report, Bloomberg NEF.
