Circuit breakers are essential components of all electrical systems providing safety and protection, controlling electrical flow, and isolating circuit elements for repair or replacement. The IULNK112-40406-2 is a commonly used circuit breaker, and its application fields and working principle are discussed in detail below.

Application Field

The IULNK112-40406-2 is mainly used in the fields of electrical engineering, electro-mechanical engineering and control engineering, automation systems, industrial machinery, and other similar industries. It can be used in a variety of power distribution systems, such as switchgear system, motor starters and electronic equipment protection circuits. Furthermore, it can also be used in electrical installation projects at home.

Working Principle

The working principle of the IULNK112-40406-2 is based on the Joule\'s Law, which states that the current passing through a conductor will generate heat which increases with the increase of current intensity. When the heating exceeds the limit of the conductor, the temperature of the conductor will rise to a certain limit, at which the circuit breaker trips. As a result, the current flow is cut off and the connected machine or equipment are protected from any further damage.

The IULNK112-40406-2 is equipped with high performance trip module, which guarantees the quick response to the cutoff and prevents over-current from burning electronic devices or other parts. Moreover, it has a higher insulation resistance and breakdown voltage than general circuits breakers. This ensures that no leakage current passes through and the protection function works more precisely and safely.

Other Features

In addition to its quick response capability, the IULNK112-40406-2 also offers a number of other features. It has a small body size design, integrating multiple terminals in a single unit, reducing wiring and installation workload. Furthermore, its operating handle can indicate the ON/OFF status of the circuit breaker and can be locked for prevention of operation by unauthorized personnel.

The IULNK112-40406-2 is designed for easy maintenance and replacement, and features a wear-resistant contact material, which can be easily replaced in case of contact abrasion. To ensure the high standard of safety, it is also equipped with arc extinction device, providing a safe and reliable solution to all types of circuit protection requirements.

To sum up, the IULNK112-40406-2 is an essential component for circuit protection, offering a wide range of features to ensure safe and reliable operation. It is especially suitable for use in automated industries, home electrical installatio projects and other similar applications.
