What are the top ten brands of circuit breakers?

Changshu Switch Co., Ltd., Shanghai People's Electric Appliance Factory Co., Ltd., Shanghai Liangxin Electric Appliance Co., Ltd., Shanghai Huatong Electric Appliance Co., Ltd., Guizhou Changzheng Electric Appliance Co., Ltd., Hangzhou Zhijiang Switch Co., Ltd., Beijing Beiyuan, Tianshui 2 13, etc. These are all domestic first-line brands, Zheng Tai, Delixi and Tianzheng, mainly engaged in low-end products to save finished products and compete by price, ABB, Schneider, Siemens and Rogland. Low-voltage products are very mature. I feel that domestic first-line brands are very good, and the quality is basically the same as that of joint ventures, with the highest cost performance.
