Wedoany.com Report on Mar 6th, Siemens Smart Infrastructure announced an expansion of its portfolio of industrial control and protection devices with new functions for the semiconductor-based SENTRON electronic circuit protection device (ECPD) and the first-time release of the SIRIUS 3RW5 -Z R11 refurbished soft starter, a product that follows circular economy principles. These initiatives aim to help industrial customers enhance electrical safety, increase system availability, and reduce environmental impact.
The SENTRON ECPD, launched in 2024, offers electronic switching that is up to 1000 times faster to reduce short-circuit risks and protect systems. It integrates over 10 configurable functions, can reduce switchgear space by up to 80%, and supports parameter adjustments via software. In the future, a single-phase version will integrate residual current monitoring (RCM), enabling continuous monitoring of circuit conditions for early fault detection and ensuring uninterrupted system operation. This function is suitable for demanding scenarios such as data centers, exhibitions, and industrial applications, and can simplify maintenance processes.
For high-voltage systems (400V/32A/50 Hz), Siemens plans to introduce a three-phase version of the SENTRON ECPD, applicable in infrastructure and industrial sectors such as conveyor belts, elevators, heat pumps, air conditioning, and UPS systems.
"Siemens is leveraging advanced semiconductor technology to redefine industry standards for circuit protection," said Andreas Matthé, CEO of Electrical Products at Siemens Smart Infrastructure. "Our SENTRON ECPD is proof of this leadership, offering unparalleled speed, precision, and a compact design to ensure maximum uptime and protection for our customers' infrastructure."
On the sustainability front, Siemens will launch the circular, low-carbon SIRIUS 3RW5 -Z R11 refurbished soft starter at the Light & Building trade fair in 2026. This product is made by refurbishing used devices, typically reducing CO2 emissions by up to 50% compared to new devices, a process transparently documented through an Environmental Product Declaration (EPD).
The refurbishment process includes comprehensive testing and replacement of key components, ensuring product performance meets new device standards and carries CE certification. Its modular design supports easy disassembly and repair, providing usage data to enable a second remanufacturing cycle. A unique ID Link QR code ensures product traceability and, combined with an Asset Administration Shell (AAS) and Distributed Ledger Technology (DLT: IOTA), lays the foundation for a Digital Product Passport (DPP) compliant with EU regulations.
