BYW1 ACB Intelligent Universal Air Circuit Breaker

Product Features 

• The BYW1 series intelligent universal air circuit breaker (ACB) is designed for use in power distribution networks with a frequency of 50Hz, a rated voltage up to 660V/690V, and rated currents up to 6300A. It is primarily used for electrical power distribution and protection against various faults such as overload, undervoltage, short circuit, and single-phase ground faults, ensuring safe and efficient operation of electrical systems in industrial and commercial applications.
• The BYW1 series ACB incorporates advanced intelligent protection, enabling accurate and selective fault detection. This feature helps improve the reliability of the power supply by quickly identifying faults and preventing unnecessary power cuts, which minimizes downtime and enhances operational efficiency. Designed to meet the needs of control centers and automated systems, the BYW1 series ACB supports "Four Remotes" functionality, which includes remote control, remote signaling, remote regulation, and remote monitoring. This is achieved through an open communication interface, allowing seamless integration with modern automation systems.
• The BYW1 series ACB is capable of withstanding an impulse voltage of up to 8000V at an altitude of 2,000 meters, with the ability to withstand voltages up to 12,000V at higher altitudes, ensuring it can operate effectively even in demanding environments with varying atmospheric conditions. In addition to its intelligent protection features, the BYW1 series ACB can function as an isolator without the need for an intelligent controller and sensor. This versatility makes it adaptable to various applications, providing both protection and isolation for circuits in different power distribution setups.
• The BYW1 series ACB is ideal for power distribution in commercial and industrial facilities, including control systems, automation, and high-power equipment. Its ability to protect against multiple faults, combined with intelligent control options, makes it a highly reliable and efficient choice for ensuring the safety and stability of electrical systems.
