The CYW1 series air circuit breakers are designed for distribution networks operating at an AC frequency of 50Hz or 60Hz. They are suitable for systems with a rated voltage of 400V or 690V and a rated current up to 6300A. These circuit breakers are primarily used for the distribution of electric energy and to provide protection against various faults in power equipment and lines.
Protection Functions:
These circuit breakers offer comprehensive protection functions, including:
* Overload Protection: They protect against excessive currents that can occur due to overload conditions in the electrical system.
* Undervoltage Protection: The circuit breakers safeguard against voltage drops below the acceptable range, ensuring the stability and reliability of the power supply.
* Short Circuit Protection: They detect and interrupt high currents caused by short circuits, preventing damage to the equipment and electrical lines.
* Single-Phase Grounding Hazard Protection: The circuit breakers provide protection against faults such as single-phase grounding, reducing the risk of electrical hazards.
CYW1 Series Air Circuit Breakers Features
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. They are capable of handling rated voltages of 400V or 690V and rated currents up to 6300A.
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. 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.
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.
Standards Compliance: The CYW1 series air circuit breakers conform to international standards, including IEC60947-2 and the GB/T14048.2-2008 standard.
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. They incorporate intelligent and selective protection functions, improving the reliability of the power supply and minimizing power outages. These circuit breakers have a wide range of applications and comply with recognized international standards.
