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.\u00a0<\/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.\u00a0<\/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.\u00a0<\/span><\/span>They incorporate intelligent and selective protection functions, improving the reliability of the power supply and minimizing power outages.\u00a0<\/span><\/span>These circuit breakers have a wide range of applications and comply with recognized international standards.<\/span><\/span><\/div>\n
