Siemens Unveils Groundbreaking Circuit Breaker with Biomass-Balanced Plastics

(IN BRIEF) Siemens Smart Infrastructure and BASF have partnered to introduce a groundbreaking innovation in electrical safety products, unveiling the first circuit breaker to incorporate components made from biomass-balanced plastics. The SIRIUS 3RV2 circuit breaker utilizes materials derived from renewable sources, such as agricultural waste, in place of fossil feedstock, resulting in a significant reduction of carbon dioxide emissions by approximately 270 tons annually. This collaboration aligns with Siemens’ sustainability goals, aiming for a 1.5°C science-based decarbonization target and robust eco-design for all relevant product families by 2030. The circuit breaker’s introduction marks a milestone in sustainable manufacturing practices, demonstrating Siemens’ commitment to resource efficiency and environmental responsibility.

(PRESS RELEASE) ZUG, 10-Jun-2024 — /EuropaWire/ — Siemens Smart Infrastructure and BASF jointly announced today a significant milestone in sustainable innovation with the introduction of the first electrical safety product integrating components crafted from biomass-balanced plastics. The SIRIUS 3RV2 circuit breaker, a vital element in industrial and infrastructure applications, now utilizes Ultramid® BMBcertTM and Ultradur® BMBcertTM materials from BASF, replacing fossil feedstock with biomethane derived from renewable sources like agricultural waste.

This groundbreaking transition in the production of SIRIUS 3RV2 circuit breakers marks a significant reduction in carbon dioxide emissions by approximately 270 tons per year. It aligns with Siemens’ sustainability objectives within its DEGREE framework, aiming for a 1.5°C science-based decarbonization target and robust eco-design for 100 percent of relevant product families by 2030.

The incorporation of sustainable materials is a pivotal step in Siemens’ commitment to resource efficiency and decarbonization. Following the success of the SIRIUS 3RV2 circuit breaker, Siemens plans to expand the use of sustainable materials across its broader SIRIUS industrial controls portfolio, emphasizing the role of materials in reducing carbon emissions and conserving natural resources.

The SIRIUS 3RV2 circuit breaker meets the rigorous criteria of the Siemens EcoTech label, providing customers with comprehensive insights into product performance and environmental impact. Besides featuring biomass-balanced plastic components, the product boasts lower power consumption over its lifetime compared to its predecessor, contributing to a circular economy and a more sustainable future.

Andreas Matthé, CEO of Electrical Products at Siemens Smart Infrastructure, expressed the importance of collaboration with BASF in advancing sustainable plastics innovation. BASF’s commitment to renewable and recycled raw materials aligns with the circular economy goals, gradually replacing fossil raw materials with bio-based and recycled feedstock.

Martin Jung, President of BASF Performance Materials, highlighted the mass balance approach as a game-changing solution for sustainable production processes, enabling the gradual replacement of fossil raw materials with alternative sources like biomethane and bio-naphtha.

The SIRIUS 3RV2 circuit breaker’s innovative use of sustainable materials without compromising safety functionality and performance underscores Siemens’ dedication to sustainability and safety in industrial and infrastructure applications.

Circuit breakers play a crucial role in safeguarding factories and buildings worldwide, protecting machinery and electrical cables from faults like short circuits. The SIRIUS 3RV2 circuit breaker, featuring sustainable plastic components, will be showcased for the first time at the ACHEMA trade fair in Frankfurt, offering visitors an opportunity to learn more about Siemens EcoTech and sustainable innovation in electrical safety products.
