Circuit Breakers are critical components in virtually every electrical system. As such, it is important to understand their application field and working principles for a successful installation. The IUGH666-1-41-5.00-AQ-90 is an example of a circuit breaker designed for specific applications and functions.

The IUGH666-1-41-5.00-AQ-90 is a three-phase thermal-magnetic breaker that has been designed to provide reliable protection and isolation in industrial or commercial installations. It has an AC/DC rating of 5.00A and features six trip curves for overcurrent protection. It is protected against both overloads and short circuits, providing instantaneous protection as well as thermal protection from overcurrents. The maximum voltage that the breaker can handle is 277VAC or 600VAC, depending on the configuration.

The IUGH666-1-41-5.00-AQ-90 features a thermomagnetic tripping curve that completely covers the overload protection range from below 5A to more than 10A. It works by measuring current levels and detecting whether the current exceeds a preset level. When this level is exceeded, the breaker trips and shuts off the power to the circuit. This tripping mechanism prevents the system from experiencing long-term damages due to overloads.

The thermal-magnetic design also enables the breaker to provide short-circuit protection. When a short-circuit is detected, the breaker trips to prevent the system from experiencing an increased power surge that could potentially damage equipment. The breaker also works as an isolation switch, providing the user with the ability to safely shut off the power to any connected equipment. This makes it easier to service and maintain the system without having to worry about any potential harm from electrical power.

The IUGH666-1-41-5.00-AQ-90 has a wide variety of applications, including substations, commercial buildings, industrial sites, and data centers. It has been designed for use with medium-voltage applications such as overhead lines, gas, and oil pipelines, industrial machinery, and other electrical installations. Its wide range of features makes it ideal for providing protection and isolation for systems in these applications.

Overall, the IUGH666-1-41-5.00-AQ-90 is an excellent example of a circuit breaker designed for specific applications and functions. This type of breaker is designed to provide reliable and effective protection and isolation from both overcurrents and short circuits. Its thermal-magnetic design makes it well suited for medium voltage applications, making it an essential component in electrical systems for industrial, commercial, and data center applications.
