Singapore: ABB has launched its latest generation of low-voltage power distribution equipment designed to meet the rising electrical demands of artificial-intelligence-driven data centres.
The upgraded MNS switchgear, incorporating the new SACE Emax 3 air circuit breaker, introduces advanced sensing, control, and cybersecurity features within a compact footprint. It was unveiled at Data Center World Asia in Singapore and is aimed at operators preparing for rapid growth in computing and energy requirements, with global data-centre capacity projected to increase from 80 GW in 2024 to over 220 GW by 2030.
The new system embeds real-time intelligence within the switchgear, enabling continuous monitoring of load balance, voltage stability, and temperature fluctuations. This integration allows early detection of potential faults and supports targeted maintenance to minimise downtime.
According to ABB, the Emax 3 is the first circuit breaker to achieve IEC 62443 SL2 cybersecurity certification, offering protection against unauthorised access and operational errors. It also includes a built-in power-quality analyser for tracking parameters such as harmonic distortion and voltage variation—critical for maintaining stability in high-density computing environments.
The modular design eliminates the need for multiple subsystems, simplifying maintenance and improving energy efficiency. Combining protection, control, and monitoring in a single unit helps data-centre operators better align power distribution with fluctuating AI workloads while maintaining uptime.
ABB’s development reflects the industry’s wider shift toward integrated, intelligent, and cybersecure electrical infrastructure as global data-centre expansion accelerates. The technology is expected to play a growing role in supporting the next generation of energy-intensive digital operations and AI processing facilities.
