Circuit breakers play an indispensable role in the power distribution network. CB1921-15 is one of the most advanced circuit breakers currently on the market. Specializing in high power applications, it is designed not only to protect the electrical system from overloads and short circuits, but also to provide an easy-to-use and reliable solution for system-level fault protection.The CB1921-15 is primarily designed for underground applications in transformer protection and power distribution systems, with a rated breaking capacity of 105 kA at 460 V. It is also suitable for low voltage applications. It is especially suitable for large-scale properties such as hospitals, commercial buildings and shopping centers.The CB1921-15 is designed to detect both current and voltage abnormalities, ensuring that the power grid is not compromised by internal or external disturbances. Its operating principle is based on the current-limiting ability of a partially-tandem-connected transformer. This allows the circuit breaker to control the fault current while keeping the voltage on the line stable during a fault.The CB1921-15 is equipped with self-clearing and self-operating mechanisms to ensure that the circuit breaker operates reliably. It is capable of interrupting a fault current at the maximum rated short-time current (Icn) for 0.5 seconds. The CB1921-15 is also designed with a built-in, digitally-controlled motor protection system that monitors each motor\'s temperature, improving overall motor protection and preventing motor breakdowns.Our CB1921-15 circuit breaker is designed with a series of external accessories to further improve performance, such as a current transformer, relay, overvoltage detector, and remote operating device. The CB1921-15 and its accessories have been rigorously tested to ensure high levels of safety, reliability, and accuracy of performance.In conclusion, the CB1921-15 is an advanced, reliable and resilient circuit breaker that provides protection and convenience in power distribution networks. It is designed to provide protection from both current and voltage disturbances, ensuring that the power grid is kept as safe and stable as possible. The CB1921-15 and its accessories will provide power users with a safe and reliable solution for their network protection needs.
