Delixi CDW3 series ACB Air Circuit Breaker

Here is an introduction to the Delixi CDW3 series and a list of its models:

The CDW3 series is a type of air circuit breaker1. It has a rated current ranging from 400A to 6300A and a rated operating voltage of 415V/690V AC, suitable for AC 50Hz/60Hz and extreme environmental conditions from -40°C to 70°C.

This series of circuit breakers is mainly used in power distribution networks to distribute electrical energy and protect lines and power equipment from overload, undervoltage, short - circuit, single - phase grounding and other faults. It can be widely applied to power stations, factories, mines, and modern high-rise buildings, especially in the power distribution systems of intelligent buildings. It complies with the standards of GB14048.2 and IEC/EN 60947-22.

The CDW3 series circuit breakers have the following characteristics:

• High breaking capacity: They can handle high - current faults, ensuring the safety and reliability of the power distribution system.

• Good mechanical strength: With a robust structure, they can withstand the impact and vibration during operation.

• Versatile installation methods: They are available in both fixed and draw-out types, and support horizontal back - connection and vertical back - connection, providing flexibility for different installation requirements.

• Complete protection functions: They are equipped with various protection functions such as overload protection, short - circuit protection, undervoltage protection, and single - phase ground fault protection, which can effectively protect the safety of power equipment and lines.
