Siemens Launches Refurbished Soft-Starter and Advanced ECPDs Reducing Emissions and Enhancing Circuit Protection

SEMICONDUCTOR

Siemens Smart Infrastructure has launched a refurbished soft-starter that can cut CO₂ emissions by up to 50% compared to new models. The Sirius 3RW5-Z R11 soft-starter is designed with a modular structure for easy dismantling and repair, and it meets new device standards with CE certification.

Siemens also introduced semiconductor-based electronic circuit protection devices (ECPDs), which are up to 1,000 times faster than electromechanical devices, thereby reducing short-circuit energy. Siemens plans to launch three-phase and single-phase ECPDs aimed at industrial applications, which will enhance circuit protection and operational efficiency.
