Circuit breakers are an essential component for any electrical system, providing a fast and efficient means to protect electrical circuits and systems from unreasonable current and voltage spikes. IUGN266-39022-1 is one such device that is used to isolate the equipment from the high-voltage power line in the event of a sudden fault. This particular model finds application in industrial and commercial distribution systems, and is designed to offer reliable protection for both personnel and equipment.

The IUGN266-39022-1 is a 5-phase circuit breaker and belongs to a specialized range of circuit breakers manufactured by the global company, Schneider Electric. Designed for high current ratings as high as 4000 A and high voltage ratings up to 690 V, this particular circuit breaker is typically used in several industrial and commercial settings. Typical application areas include foundries, hospitals, boat lifts and numerous other industrial and commercial power distribution systems.

The IUGN266-39022-1 circuit breaker is equipped with a combination of both technologies, namely air circuit breakers (ACB) and Vacuum Circuit Breaker (VCB). Air Circuit Breaker (ACB) has contacts that are mechanically operated and are used to break the arc occurring between them. An air circuit is normally installed outside and this effectively reduces the internal arcing and risk of an electric shock. Alternatively, Vacuum Circuit Breaker (VCB) has an electric contact that is operated by vacuum. This technology is highly reliable as any fault detected within the system is immediately switched off and power to the load is cut off without causing any sparks.

The working principle of the IUGN266-39022-1 circuit breaker further enhances its safety characteristics. It has an advanced trip free mechanism that ensures that the breaker won’t reset itself should any fault occur and continues to be in the tripped state. The breaker is designed to be very responsive; in the event of an over-current, it trips and isolates the overloaded circuit from the live power line. This helps protect the equipment and provides a safe environment for personnel.

The IUGN266-39022-1 circuit breaker is a highly reliable and efficient device that provides safe power distribution in almost any environment. The combination of air circuit breaker and vacuum circuit breaker ensures that it is capable to handle any overload current and provide a reliable and quick protection from any unexpected conditions. The advanced trip free mechanism guarantees that the breaker stays in a tripped state until manually reset, making this a highly effective safety device.
