Circuit breakers have become an integral part of the modern electrical grid for their functions of automatically breaking off the electricity supply during an overload or short-circuiting. They bring convenience to the users with their ability to protect and isolate vulnerable parts of an electrical network from surges and other related damages. Among the circuit breakers, the IUGN6-1-62-7.50 breaker is one of the most commonly used models.

The IUGN6-1-62-7.50 circuit breaker is a medium-voltage breaker (MV), suitable for utilization voltages of up to 6 kV and rated short-circuit rupturing capacity up to 20 kA. With a spring-operated mechanism and single-phase bimetal Strip, the IUGN6-1-62-7.50 breaker applies a high-speed operating principle.

The core element of the IUGN6-1-62-7.50 breaker is a heat-sensitive bimetallic strip, which deforms when heated. The strip is attached to a fixed part of the breaker and to an armature which has an opposite motion to the strip. As the current surge, the bimetallic strips generates quickly a strong torque from the heat produced, moving the armature against the spring force. This ensures that the contacts of the breaker disconnect before the total current exceeds the allowable maximum. Meanwhile, the bimetallic strip also pushes the fixed contacts simultaneously, thus moving both parts of the breaker from the contact position and protecting the circuit from overvoltage.

The IUGN6-1-62-7.50 is commonly used in industrial applications that require medium-voltage switching and protection, such as electric motors, drive systems, and high-capacity pumps. The breaker is usually designed as a three-pole device, allowing a flexible installation process, easy operation, and reliable performance. Besides, its sophisticated arc quenching chamber is suitable for robust use at a broad range of operating temperatures.

Furthermore, the IUGN6-1-62-7.50 circuit breaker also comes with a range of optional features, including a fuse indication, auxiliary contacts, a remote electric reset button, and a current monitor. The highly customizable features of the IUGN6-1-62-7.50 make it suitable for a range of complex applications where space is limited or the installation is difficult to achieve with standard units.

In summary, the IUGN6-1-62-7.50 is an advanced medium-voltage circuit breaker that meets the highest performance standards of industrial use. Its fast-acting spring mechanism and advanced bimetallic strip containment technology ensure fast and reliable circuit protection for various applications. With a broad selection of accessories tailored to specific requirements, the IUGN6-1-62-7.50 provides enhanced safety, reliability, and flexibility for users who need reliable protection and isolation of their electrical networks.
