Siemens and DOMO Chemicals join forces to drive sustainability in the electrical industry
The SENTRON 5SV3 residual current circuit breaker (RCCB), type A/AC is the first Siemens product using TECHNYL® 4EARTH® from DOMO Chemicals, a high-performance 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 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.
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 significantly reduces the environmental
impact of the manufacturing process without compromising performance or
quality.
Siemens: Advancing circularity in electrical safety
“We want to lead the industry with smart and
sustainable technology,” said Andreas Matthé, CEO of Electrical Products at
Siemens Smart Infrastructure. “It’s our ‘new normal’ to deploy as much
sustainable material as possible for each new product to support our customers
in achieving both optimized operations and their environmental goals. We are
delighted to promote circularity and responsible use of resources in the
electrical and electronics industry together with our partner DOMO Chemicals”.
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, undervoltage releases, and more. This unified system of
function extensions ensures that machines and switchboards remain productive
and cost-effective for longer periods.

Innovative 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.
“At DOMO Chemicals, our ambition is to
support our customers in achieving a lower carbon footprint without
compromising performance. We are thrilled to partner with Siemens to deliver
innovative and sustainable solutions that meet the growing demand for environmentally
friendly materials,” said Juha Jokinen, Chief Commercial Officer Engineered
Materials at DOMO Chemicals. “With our TECHNYL®4EARTH®, we combine high
performance with various CO₂ reduction targets. By leveraging our
expertise in polyamide technology alongside Siemens’ strong sustainability
focus, we aim to make a positive impact on the electrical industry, a dynamic
and rapidly growing market.”
DOMO’s extensive sustainable portfolio for the E&E market
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.
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.
DOMO Chemicals and Siemens Smart
Infrastructure are committed to expanding the availability of this sustainable
material to meet the global demand for sustainable solutions in the electrical
and electronics industry, in line with changing consumer behavior. DOMO
Chemicals' advanced recycling technology, coupled with its strong supplier
network, enables the company to offer a wide range of sustainable polyamide
solutions. The successful development of this flame-retardant PA6 compound
demonstrates the potential of depolymerization as a promising technology for
creating high-performance, environmentally friendly materials, supported by leading
solution providers such as Siemens Smart Infrastructure.
