Kuala lumpur: ABB has unveiled the next generation of its flagship air circuit breaker, the SACE Emax 3, aimed at supporting facilities with high power demands such as data centres, advanced manufacturing plants, hospitals and airports. The Emax 3, successor to the Emax 2 smart circuit breaker, introduces enhanced features to address growing concerns over grid stability, cybersecurity, and the rising energy consumption driven by artificial intelligence (AI) technologies in data centres.
According to BERNAMA News Agency, the Emax 3 is equipped with advanced power sensors and real-time analytics to monitor power usage, system health, and environmental factors including temperature. The collected data is accessible remotely or via the device’s touchscreen, providing users with live system insights, alerts, and predictive maintenance recommendations.
ABB Electrification Smart Power President, Massimiliano Cifalitti, highlighted the importance of resilient electrical systems for critical infrastructure. He noted that as demand for advanced electrification continues to grow, Emax 3 enables customers to adapt to changing power needs and protect uptime. Meanwhile, ABB Electrification Head of Distribution and Energy Management, Lara Cortinovis, pointed out that grid instability, human error, and cyber threats are key concerns among customers, with power outages posing significant financial risks to operations.
ABB’s SACE-brand circuit breakers are globally recognized for their performance, with millions installed in critical facilities worldwide. Notably, the Emax 3 is the world’s first air circuit breaker certified with Security Level 2 IEC 62443 cybersecurity standards and features a fully integrated arc flash detection system, enhancing safety and system reliability.
According to Uptime Intelligence’s 2025 Outages Analysis, more than half of digital infrastructure disruptions are caused by power failures, with over 50 percent of major incidents incurring losses exceeding US$100,000. Additionally, one in five data centre operators reported their latest major outage cost over US$1 million. ABB is a global technology leader in electrification and automation with a workforce of about 110,000 employees worldwide. Its shares are listed on the SIX Swiss Exchange and Nasdaq Stockholm.
