IUGH66-1-42-20.0-A-00

Introduction to Circuit Breakers

Circuit breakers are electrical components designed to automatically interrupt an electrical circuit by disconnecting the power supply downstream of the breakers when an overload or short circuit condition is detected. This process effectively prevents further damage to the electrical system, making them an essential component in almost any electrical system, especially those with a high degree of automation. The particular model IUGH66-1-42-20.0-A-00 is a General Electric circuit breaker, and while its exact application and working principle will be discussed shortly, it should be noted that its primary purpose is the same as any other standard circuit breaker, which is to protect the electrical equipment downstream from power spikes and short circuits.

Application Field and Working Principle

The IUGH66-1-42-20.0-A-00 circuit breaker is designed to be a compact, lightweight, and reliable high-current circuit interrupting device. It is rated for use at 600VAC, and is capable of interrupting a maximum current of 20kAIC. This model is suitable for use in industrial, commercial, and residential applications, such as in motor control circuits, lighting circuits, and air conditioning applications. Additionally, it is rated for use in hazardous locations, so it can also be used in locations where flammable or explosive materials are present.

The working principle of this circuit breaker is relatively simple. When the current flowing through the circuit exceeds the maximum rated current for the breaker, the breaker’s internal mechanisms will detect the overload and automatically open the circuit. This prevents further damage to the electrical system and its components. Once the overload has been cleared, the breaker can be manually reset by pushing the reset button, which will close the circuit and allow power to flow again.

Conclusion

The IUGH66-1-42-20.0-A-00 is a General Electric circuit breaker that is designed to provide reliable overload and short circuit protection for motor control circuits, lighting circuits, and air conditioning applications. It is rated for use at 600VAC and can interrupt a maximum current of 20kAIC, making it suitable for residential, commercial, and industrial applications, as well as hazardous locations. Its working principle is simple – when the current flowing through the circuit exceeds the maximum rated current, the breaker will detect the overload and automatically open the circuit, protecting the downstream electrical equipment. Once the overload has been cleared, the breaker can then be reset and power restored.
