DOMO Chemicals developed and validated a TECHNYL 4EARTH PA6 material for Siemens.
Siemens Smart Infrastructure and DOMO Chemicals have collaborated to develop sustainable materials for the electrical industry. DOMO Chemicals has developed and tested a TECHNYL 4EARTH polyamide 6 (PA6) material for Siemens applications, incorporating recycled content and advanced flame-retardant technology.
The SENTRON 5SV3 residual current circuit breaker (RCCB), type A/AC is the first Siemens product using TECHNYL 4EARTH from DOMO Chemicals, a polyamide made from 50% recycled nylon. The recycled material offers the same performance and quality as conventional materials.
Siemens will be using this material for electrical safety products for the first time. This 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 important in residential and commercial electrical installations.
Composed of 50 percent 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 reduces the environmental impact of the manufacturing process without compromising performance or quality.
Siemens: Advancing circularity in electrical safety
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 10,000 operating cycles, these devices offer better mechanical and electrical life, ensuring reliable performance and longevity. SENTRON 5SV RCCBs, type A/AC, support upgrades to existing applications with minimal modifications. The standardized accessory system allows for easy hardware upgrades, including auxiliary switches, and undervoltage releases. This system helps extend the operational life of machines and switchboards while maintaining efficiency.
Recycled material meets latest industry standards
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.
