Circuit Breakers have been a vital part of electrical systems since the late 19th century. An important advance in design and functionality was the IELHK11-1-52F-40.0-01-V, which is still widely used today. This article will discuss the application field and working principle of the IELHK11-1-52F-40.0-01-V.

Application field

The IELHK11-1-52F-40.0-01-V is an incredibly versatile circuit breaker. It can be used in a variety of settings, including residential, commercial, industrial, and maritime applications. It’s approved for use in most countries, making it an ideal option in global applications as well. It can be used to protect electrical devices from damage due to overcurrents, as well as to isolate parts of the electrical system to ensure safety when working on them or replacing them. Additionally, its wide range of sizes and capacities make it a suitable option for a variety of power requirements.

Working principle

The IELHK11-1-52F-40.0-01-V is a thermal-magnetic circuit breaker, which means it has both thermal and magnetic components. It functions in three distinct stages: Thermal stage, Pre-trip stage, and Trip stage. In the thermal stage, the heat generated by the current that passes through the circuit breaker’s terminal heats a bi-metallic strip included in the housing. Once the metallic strip reaches a predetermined temperature, it causes the breaker to close, thus cutting off the power supply and preventing the device from further damage.

The pre-trip stage involves a magnetic core that is activated by the supply current. Once it reaches a certain magnitude, the magnetic core causes the trip bar to move. This movement is then transferred to the thermal contacts, thus initiating the release mechanism to open the circuit.

Finally, the trip stage is the narrowest point in the trip curve and signifies the point at which the circuit breaker trips. When this occurs, the breaker will snap open, cutting off the power supply and protecting the electrical system.

Conclusion

The IELHK11-1-52F-40.0-01-V is an incredibly versatile and reliable circuit breaker, suitable for a variety of applications. Its thermal-magnetic design and wide range of sizes and capacities make it an ideal choice for both residential and commercial settings. Additionally, its three-stage operation ensures the safety of any electrical system it is installed in. As such, the IELHK11-1-52F-40.0-01-V is a great choice for anyone looking for a reliable and robust circuit breaker.
