<\/p>\n

The CYW1 series air circuit breakers are designed for distribution networks operating at an AC frequency of 50Hz or 60Hz. <\/span><\/span>They are suitable for systems with a rated voltage of 400V or 690V and a rated current up to 6300A. <\/span><\/span>These circuit breakers are primarily used for the distribution of electric energy and to provide protection against various faults in power equipment and lines.<\/span><\/span><\/div>\n
<\/div>\n
Protection Functions:<\/span><\/span><\/div>\n
<\/div>\n
These circuit breakers offer comprehensive protection functions, including: <\/span><\/span><\/div>\n
* Overload Protection: They protect against excessive currents that can occur due to overload conditions in the electrical system.<\/span><\/span><\/div>\n
* Undervoltage Protection: The circuit breakers safeguard against voltage drops below the acceptable range, ensuring the stability and reliability of the power supply.<\/span><\/span><\/div>\n
* Short Circuit Protection: They detect and interrupt high currents caused by short circuits, preventing damage to the equipment and electrical lines.<\/span><\/span><\/div>\n
* Single-Phase Grounding Hazard Protection: The circuit breakers provide protection against faults such as single-phase grounding, reducing the risk of electrical hazards.<\/span><\/span><\/div>\n

CYW1 Series Air Circuit Breakers Features<\/span><\/span><\/div>\n
<\/div>\n
Suitable for Distribution Networks: The CYW1 series air circuit breakers are specifically designed for distribution networks operating at an AC frequency of 50Hz or 60Hz. <\/span><\/span>They are capable of handling rated voltages of 400V or 690V and rated currents up to 6300A.<\/span><\/span><\/div>\n
<\/div>\n
Intelligent and Selective Protection: The CYW1 series circuit breakers are equipped with intelligent protection functions, allowing for enhanced reliability of the power supply and minimizing unnecessary power outages. <\/span><\/span>They also feature selective protection capabilities, ensuring that only the affected portion of the system is isolated during a fault, while the rest of the system remains operational.<\/span><\/span><\/div>\n
<\/div>\n
Widely Applicable: These circuit breakers find application in various settings, including power stations, factories, ore mountains (especially for 690V systems), and power distribution systems in modern high-rise buildings, particularly intelligent buildings.<\/span><\/span><\/div>\n
<\/div>\n
Standards Compliance: The CYW1 series air circuit breakers conform to international standards, including IEC60947-2 and the GB\/T14048.2-2008 standard.<\/span><\/span><\/div>\n
<\/div>\n
In summary, the CYW1 series air circuit breakers are designed for distribution networks and offer protection against overload, undervoltage, short circuits, and other electrical faults. <\/span><\/span>They incorporate intelligent and selective protection functions, improving the reliability of the power supply and minimizing power outages. <\/span><\/span>These circuit breakers have a wide range of applications and comply with recognized international standards.<\/span><\/span><\/div>\n
