CW3X-1600 Intelligent universal circuit breakerDetailed product description：

CW3X-1600 is the first domestically developed high breaking and current limiting universal circuit breaker by Changshu Switchgear Manufacturing Co., Ltd., which combines the development experience of universal circuit breakers and molded case circuit breakers. The product has small size, high breaking capacity, rich functions, and complete protection, and its performance indicators have reached the international advanced level. The coordination between the current limiting CW3X-1600 and the lower level CM5 molded case circuit breaker meets the complete selectivity requirements of Appendix A of GB14048.2.
CW3X-1600 is suitable for various low-voltage distribution fields, not only for protecting power lines, but also for protecting equipment such as motors and generators. The product can be applied to new energy fields such as branch circuits of large capacity transformers, centralized load control, long cable power supply, and photovoltaic power generation.
