  • 产品名称: CW3X-1600 Intelligent Universal Circuit Breaker

Overview

CW3X-1600 is a national initiative high-breaking current-limiting universal circuit breaker newly launched by integrating the development experience of universal circuit breakers and moulded case circuit breakers of Changshu Switch Manufacturing Co., Ltd., and features small size, high breaking capacity, abundant functions and complete protection range, with the performance indexes reaching the international advanced level. The current-limiting CW3X-1600 is matched with the subordinate CM5 moulded case circuit breaker, to meet the complete selectivity requirements in appendix A of GB14048.2.
CW3X-1600 is suitable for various low-voltage distribution fields, which can not only protect circuits but also can protect motors, generators and other kinds of equipment. The product can be applied to branch circuits of large-capacity transformers, concentrated control over loads, power supply with long power cables, photovoltaic power generation and other fields and occasions of new energy.
