Schneider Electric has selected DuPont™ Zytel® for the creation of a high dielectric strength housing for the high precision current (A) sensor in its new connected Masterpact MTZ circuit breaker. The application of Zytel® illustrates DuPont’s ability to provide cutting-edge materials for smart devices and the Internet of Things (IoT), and create innovative solutions to customers’ challenges. This new halogen-free and UL certified self-extinguishable grade, Zytel® FR95G25V0NH, meets Schneider Electric’s key requirements and exhibits outstanding performance over a long period of time.
Performance improvement
The use of Zytel® has resulted in a step change performance improvement of the high precision current sensor in Schneider Electric’s air circuit breaker. The Class II or Double Insulated current sensor secures Class II circuit breaker as per International Electrotechnical Commission (IEC) and Underwriters Laboratory (UL) standards, made possible with Zytel®. DuPont and Schneider Electric worked together on developing this solution, which combines laser-weldability with long term aging performance.
