Air Circuit Breaker Integrates Cybersecurity and Analytics

ABB has launched its SACE Emax 3 air circuit breaker in Vietnam at Power Innovation Day 2026, targeting high-power applications such as data centers, smart factories, and critical infrastructure. The system integrates protection, measurement, and digital analytics to address increasing demands on electrical networks driven by digitalization and AI workloads.

Real-time monitoring for power system reliability
The SACE Emax 3 incorporates high-precision sensors and embedded analytics to continuously monitor electrical parameters, equipment status, and environmental conditions such as temperature. Data is accessible locally via a touchscreen interface or remotely through connected systems.

This enables early detection of anomalies, supports condition-based maintenance, and improves system continuity by reducing unplanned downtime. The integration of analytics into protection devices reflects a broader shift toward intelligent power distribution within industrial automation environments.

Cybersecurity compliance for connected infrastructure
The device is certified to IEC 62443 Level 2, a standard for cybersecurity in industrial automation and control systems. This ensures that the circuit breaker can operate securely within networked environments, where power distribution equipment is increasingly connected to supervisory and control platforms.

Cybersecurity is becoming a critical requirement in sectors such as data centers and industrial facilities, where power systems are integrated into digital infrastructure.

Integrated protection and measurement capabilities
The circuit breaker combines multiple functions within a single platform:

The inclusion of arc detection directly within the breaker reduces the need for separate protection systems and improves response times in fault scenarios.

Application in high-demand energy environments
The system is designed for deployment in environments with high reliability requirements, including:

In these applications, maintaining uninterrupted power supply and ensuring rapid fault response are essential for operational continuity.

Role in digital power infrastructure
The introduction of the SACE Emax 3 aligns with the evolution of the digital supply chain and smart energy systems, where electrical infrastructure is integrated with data-driven control and monitoring platforms.

The launch also highlighted ABB’s broader portfolio, including building management and energy optimization solutions. These systems support centralized control, digital substations, and AI-based fault prediction, forming part of an interconnected industrial automation ecosystem.

As power demand increases alongside digital transformation, intelligent circuit protection systems play a central role in ensuring safe, reliable, and efficient energy distribution.
