Zhejiang Yingchuang Electric Co., Ltd. has made new progress in smart distribution technology. According to information published by the China National Intellectual Property Administration (CNIPA), the company’s invention patent application for an “Integrated Primary-and-Secondary Pole-Mounted Circuit Breaker” has been officially published (Publication No.: CN120497088A), with a filing date of June 2025. The patent abstract indicates that the invention relates to the field of pole-mounted circuit breaker technology, with its core innovation being a dual-drive mechanism (manual + electric) for controlling the disconnecting switch.
