Switzerland, Zurich: ABB has introduced its latest innovation in electrical protection: the SACE Emax 3 air circuit breaker, designed to enhance power resilience and stability for critical infrastructure such as data centres, advanced manufacturing plants, hospitals, and airports.
The Emax 3 succeeds the widely adopted Emax 2 and introduces cutting-edge features including predictive maintenance, real-time data analytics, and advanced sensing. This next-generation circuit breaker helps operators anticipate issues and maintain system health proactively, significantly reducing the risk of costly outages.
As power demands grow, particularly with the rise of Artificial Intelligence in data centres, the Emax 3 responds with precise load monitoring and system health assessments. Its sensors monitor power usage, temperature, and environmental conditions, providing remote alerts and on-device insights through an intuitive touchscreen interface.
Importantly, Emax 3 is the world’s first air circuit breaker to achieve IEC 62443 Security Level 2 (SL2) certification, underlining its protection against cybersecurity threats. It also features integrated arc flash detection, improving safety and operational reliability.
According to ABB, unplanned outages are increasingly costly, with many exceeding $100,000, and some over $1 M. “Solutions like Emax 3 are vital for making critical infrastructure more secure and reliable,” said Lara Cortinovis, Head of Distribution & Energy Management at ABB Electrification.
By combining smart diagnostics, digital connectivity, and cybersecurity, ABB’s SACE Emax 3 sets a new standard in intelligent power management and protection.
