MCB arc-breaking mechanisms need to handle higher breaking capacities in a confined space to minimize risks of electrical accidents. Our thermoplastic solutions enable faster arc quenching that lowers energy dissipation, and demonstrate low soot formation that improves isolation resistance after multiple short circuits. This increases the long-term reliability of the MCB. Materials offer a melting point up to 295°C, ensuring part reliability in high voltage environments. Competing solutions, including bulk moulding compounds (BMC), polyamide (PA6)/polyoxymethylene (POM) and PA6/polypropylene (PP) blends melt in this environment.
At DSM, we know there’s no room for compromise when it comes to safety. That’s why our teams collaborate with leading power distribution experts to develop thermoplastic solutions you can depend on for developing reliable, high-performance MCBs that eliminate safety risks. Our global manufacturing, research and technology and application development teams continuously optimize and re-test our materials to meet your evolving requirements, enabling you to better lead your industry.
