Circuit breakers are devices which are used to protect electrical systems from damage due to an excess of current. A 991280 is an automated, circuit-interrupting micro-switch suitable for use in medium-to-high voltage circuits. It is designed to eliminate or reduce the likelihood of shorts and arcing due to sudden fluctuations in the current demand.A 991280 uses a detect-and-delay system to trip the load within a fraction of a second when a fault in the electrical system is detected. This offers certain advantages over more traditional breakers, such as a reliable short-circuit current interruption, and a much faster breakdown response time. The 991280 also has a much lower power consumption than many alternative types of breaker.The 991280 is constructed from a combination of semiconductor materials, such as silicon, gallium arsenide, and germanium, and a conductive metal such as titanium. The contact points in this device are formed from separate, side-by-side electrodes, which can be adjusted for different current overload ratings. This enables the breaker to be tailored to different high-voltage applications.The 991280 requires no external power for operation. Instead, it is self-powered by current passing through the electrodes on the contact points. When the predetermined current limit is exceeded, the contacts open, interrupting the current flow and providing circuit protection. This interruption is typically accomplished in under a millisecond, far faster than a manual switch.The 991280 is designed to be used in a wide variety of applications in residential, industrial, and commercial environments. It is particularly useful in protecting sensitive electronic equipment such as computers, medical devices, home automation systems, and other vulnerable electrical systems which could be damaged if subjected to excessive current.The 991280 is a durable, reliable circuit breaker which is capable of providing long-term protection for high-voltage electrical systems. It is also relatively inexpensive, making it a popular choice for both residential and commercial installations. The 991280 is easy to install and maintain, making it a great choice for any electrical system.
