Circuit breakers are devices that are intended to break the flow of current for a period of time to protect people and equipment from faults, mishaps, and other undesirable incidents. The IUGN1-1-63-2.50 is a type of circuit breaker specifically designed for medium-voltage applications with a rating of up to 15kV. This makes it suitable for both commercial and industrial applications, and it is often used in facilities such as power plants, factories, and large buildings to provide short- and long-term safety.

The IUGN1-1-63-2.50 features low voltage drop to ensure minimal disruption to power supply during a trip operation. It also has easy assembly and disassembly for maintenance purposes, as well as a wide selection of auxiliary switches for desired operations. Additionally, its high mechanical and electrical retroactivity further increases assurance for operators that their equipment is safe and reliable.

The IUGN1-1-63-2.50 operates on the general principle of overcurrent protection. When the current exceeds a certain limit, the device trips itself to break the circuit and prevent any dangerous situations from arising. This is accomplished by the movement of the closing contacts inside the breaker. As the current passes through the closing contacts, their separation creates an arc, which is extinguished when the circuit is broken.

Aside from overcurrent protection, the IUGN1-1-63-2.50 also provides overload protection. This is achieved by the heat generated from the contacts when the current exceeds the nominal value. The heat will cause the contacts to melt, thus preventing further damage. In addition, it also has high resistance to both dielectric stress and short circuit currents.

The IUGN1-1-63-2.50 has been extensively tested and certified, ensuring its compliance with international standards, such as UL1066, CSA C22.2, and IEC60947-2. Additionally, it is available in both fixed and draw-out designs, making it suitable for both indoor and outdoor applications.

In conclusion, the IUGN1-1-63-2.50 is an excellent choice for high-performance, medium-voltage circuit breaker applications. It provides overcurrent, overload, and short-circuit protection, as well as easy assembly and maintenance. Its versatile design makes it suitable for both indoor and outdoor use, and it has been extensively tested to ensure its compliance with international standards.
