Circuit breakers are the most common form of safety device in electrical engineering that are designed to protect against overloads and short circuits. The IELHK1111-30431-1-V is a particular type of circuit breaker, designed as an effective and economical solution for low-voltage applications. This article looks at the application fields and working principles for the IELHK1111-30431-1-V.

Application Fields

The IELHK1111-30431-1-V is designed for use in low-voltage applications, viewed as anything under 1000V. It is suitable as an industrial circuit breaker, ideal for electrical and electronic cooling systems in a variety of applications such as machine tools, welding systems, heat exchangers, ovens, and pumps. It is also suitable for light and consumer electronics and high-density distribution enclosures, such as those found in office buildings and telecommunication rooms.

The IELHK1111-30431-1-V is a multi-position breaker, meaning it can be mounted on a switchboard or on a door, depending on the application. It is also popular for its high short circuit current rating (SCCR), meaning it is suitable for use in tough conditions as it is able to manage high amperage fault situations. This type of circuit breaker also features an adjustable rated current. This means a single breaker can be used for different currents, allowing for maximum versatility.

Working Principle

The IELHK1111-30431-1-V is a bi-directional circuit breaker that is designed to effectively protect against both overloads and short circuits. It consists of two poles connected in series, with a bimetallic contact mounted between them. When an overload or a short circuit occurs, a bimetallic strip bends and breaks the contact between the two poles, resulting in an interruption of the electrical current. The contacts then cool off and reset when the fault has been cleared, allowing current to resume.

The IELHK1111-30431-1-V is designed for high fault current levels (up to 65,000 A) in a low-voltage environment. It features an adjustable fusing and rating component; the amperage and voltage rating can be adjusted up to 600VAC and 30A. It also includes an automatic reset feature, allowing the breaker to reset automatically (in some cases) and re-establish contact when the fault has been cleared.

The IELHK1111-30431-1-V is designed with a variety of features to further enhance the protection it offers. It includes an end-of-cycle indicator, allowing the user to determine if the breaker has successfully opened the circuit and if the fault has cleared. Additionally, integrated switches provide additional protection, sensing when faults arise in the circuit and switching the breaker off before the fault can damage the system.

Conclusion

The IELHK1111-30431-1-V is a low-voltage circuit breaker designed to be used in a variety of applications. It is a bi-directional breaker, designed to protect against overloads and short circuits. It has a short circuit current rating of 65,000 A and features an adjustable rated current, allowing the same breaker to be used for different amperages and voltages. Additionally, it comes with a range of features to further enhance the protection it provides, such as an end-of-cycle indicator and integrated switches.
