Siemens and Infineon Leverage Silicon Carbide Circuit Breaker Technology to Boost Industrial Automation and Power System Protection

Industrial Automation Power Protection Partnership Using SiC Technology

Infineon and Siemens Strengthen Control Systems Reliability in Industrial Automation

Infineon Technologies and Siemens AG are collaborating on advanced electrical protection solutions for industrial automation.
They target data centers, factories, and battery energy storage systems.
Therefore, they aim to improve system reliability in modern control systems and factory automation environments.
Infineon supplies silicon carbide (SiC) power modules to Siemens for next-generation protection devices.

This cooperation reflects rising demand for resilient industrial power infrastructure.
Moreover, electrified production systems require faster and smarter protection strategies.

Silicon Carbide Power Modules Enhance PLC and DCS Infrastructure Performance

Infineon provides 1200 V CoolSiC™ MOSFET power modules for Siemens SENTRON 3QD2 circuit breakers.
These components improve efficiency, switching speed, and power density in electrical protection systems.
In addition, they support advanced industrial automation architectures involving PLC and DCS platforms.

Siemens integrates these SiC modules into semiconductor-based circuit breaker designs.
As a result, protection systems respond faster and operate more reliably under stress conditions.

Solid-State Circuit Breakers Improve Factory Automation Safety and Speed

Traditional circuit breakers rely on mechanical switching mechanisms.
However, Siemens uses semiconductor-based solid-state circuit breaker technology in SENTRON 3QD2.

This design interrupts fault currents within microseconds.
Therefore, it performs up to 1,000 times faster than conventional protection devices.

Such speed is critical for factory automation, industrial control systems, and DC grids.
Moreover, it reduces downtime and protects sensitive equipment in high-value production environments.

Even small delays can damage systems in AI data centers and automated factories.

DC Grid Innovation Supports Industrial Automation and Energy Efficiency

Siemens expands its direct current (DC) portfolio to support future industrial automation systems.
DC architecture improves energy efficiency and reduces material consumption in infrastructure design.

Furthermore, engineers can integrate battery storage to smooth peak power demand.
This approach strengthens control systems stability across factories and energy networks.

Siemens emphasizes decarbonization and sustainable engineering through DC-based solutions.
In addition, these systems support scalable and future-ready factory automation ecosystems.

High-Speed Electrical Protection Enables Reliable Data Centers and Smart Factories

The combination of SiC modules and Siemens protection logic enhances industrial system resilience.
Data centers, manufacturing plants, and energy storage systems benefit from ultra-fast fault isolation.

Moreover, the technology improves uptime in industrial automation environments.
It also supports next-generation PLC and DCS-based distributed control architectures.

As a result, operators gain higher system availability and lower operational risk.
Therefore, industries can meet rising demand for electrification and digital transformation.
