Circuit Breakers are versatile electrical devices that provide protection, control, and isolation. A Circuit Breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload, short circuit, or other electrical incident. The IUGN66-33904-20 is an example of a Circuit Breaker and is used for applications such as industrial and commercial buildings, switching, power source distribution, and motor control.

The IUGN66-33904-20 is a 3-pole air circuit breaker with a rated voltage of 480V AC. Depending on the application, it can be configured for either manual or automatic operation. It has an AC rated current of 100 to 800 Amps and is available in 3-6kA and 10kA short-circuit ratings for complete system protection. The IUGN66-33904-20 has a standard cable compartment to allow for increased flexibility and to provide an easy connection to the main power source.

The IUGN66-33904-20 features a range of additional features to make installation and maintenance easier. The breaker has an isolation feature that allows for an isolated control circuit, making it suitable for use in multiple areas. Additionally, it has a special locking mechanism to prevent unauthorized access. It also has an adjustable coordination system to ensure proper breakers protection.

The working principle of the IUGN66-33904-20 is based on a three-phase system. When switching is required, the current passes from one of the terminals to the others by way of the "Link Terminal" Integrated within the device. As it passes through the terminal, an magnetizing inductance creates a magnetic field. When a current overload or short circuit occurs, the magnetic field pushes the trip button, resulting in the connection breaking. Once the overload or short circuit has been cleared, the breaker can be manually reset or automatically reset, depending on the setting.

The IUGN66-33904-20 circuit breaker is suitable for a variety of applications, from commercial and industrial buildings to switching, motor control, and power source distribution. The Device is designed to provide a safe and reliable circuit protection, with an adjustable coordination system for added protection, and an isolation feature to prevent unauthorized access. This breaker is easy to install and maintain, and is also cost-effective. Thanks to its durability and high performance, it is a popular choice for many different application needs.
