Sustainability in electrical industry: Siemens and DOMO Chemicals join forces
- February 27, 2025
Siemens Smart Infrastructure and DOMO Chemicals have announced a significant milestone in their joint effort to promote sustainable practices in the electrical industry.
DOMO Chemicals has successfully developed and validated a new, high-performance TECHNYL® 4EARTH® polyamide 6 (PA6) material, which incorporates recycled content and advanced flame-retardant technology, to be used for Siemens applications.
Pioneering effort
Siemens will be using this material for electrical safety products for the first time. This groundbreaking TECHNYL® 4EARTH® material, specially developed by DOMO Chemicals, will enable Siemens to produce most of the covers and housings of the Siemens SENTRON 5SV3 residual current circuit breakers (RCCB), type A/AC, while offering the same performance and quality as conventional materials, which is a prerequisite for a safety product. RCCBs enhance electrical safety by quickly disconnecting power when they detect a current imbalance, preventing electric shocks and fires. They are essential in both residential and commercial electrical installations.
Composition
Composed of 50 per cent recycled content, including chemically recycled PA6 from various post-industrial and post-consumer sources such as fibers and textile filaments, as well as glass reinforcement, the material significantly reduces the environmental impact of the manufacturing process without compromising performance or quality.
EcoTech label compliant
The SENTRON 5SV3 RCCBs, type A/AC, meet the criteria of the recently introduced Siemens EcoTech label. Besides using sustainable materials, the SENTRON RCCBs are designed to exceed the standard lifetime expectations set by IEC 61008-1. With an impressive 10,000 operating cycles, these devices offer superior mechanical and electrical life, ensuring reliable performance and longevity. With SENTRON 5SV RCCBs, type A/AC, functionality of existing applications can be enhanced effortlessly.
The standardized accessory system allows for easy hardware upgrades, including auxiliary switches, under-voltage releases, and more. This unified system of function extensions ensures that machines and switchboards remain productive and cost-effective for longer periods.
UL-certified
TECHNYL® 4EARTH® C 52G1 V25 CR GY 2747 is used for most parts of the covers and housings of these RCCBs, which are produced in high quantities. The material is also UL certified, guaranteeing its quality and safety standards. The solution uses a phosphorous and halogen-free flame-retardant system. The PA6 compound offers excellent molding and electrical properties, ensuring optimal performance in demanding applications. The material can be easily customized to match specific color requirements, in this case, light grey.
DOMO’s extensive sustainable portfolio
DOMO offers the broadest portfolio of sustainable polymers available on the market today. Its offering includes mechanically and chemically recycled solutions as well as mass balance certified options. These alternatives come with different levels of performance and environmental impact reduction and are offered based on the end customer’s application needs.
Sustainable alternatives
Leveraging its extensive experience in flame-retardant and sustainable solutions, DOMO now provides unique sustainable alternatives to the E&E market, which combine minimized CO2 impact, a substantial amount of recycled content, the ability to be colored, and laser markability, all achieved through various flame-retardant technologies. Safety remains paramount, as evidenced by the material’s UL certification, which applies to both mechanical and chemical recycled alternatives.
