Circuit breakers are important devices that protect motors, transformers, generators and other electrical equipment from damage caused by high currents or overloads. The IELHK21111-1REG4-31246-6 is a circuit breaker specifically designed for this purpose. In this article, we will look at its application field and working principle.

Application field

The IELHK21111-1REG4-31246-6 circuit breaker is typically used in a wide range of environments. It provides protection against short circuits, over-current, over-voltage, under-voltage, and overloads. Its high breaking capacity and short-circuit protection make it perfect for use in industrial, commercial, and residential environments.

The breaker can also be used in sensitive loads such as pumps, motors, and industrial machines. It is also suitable for heavy-duty applications such as substations and HV/LV distribution networks. Furthermore, the breaker can be used to provide protection from lightning strikes, minimizing damage and preventing fire hazards.

Working principle

The IELHK21111-1REG4-31246-6 circuit breaker utilizes an electromagnetically operated contact system. This system is designed to open and close at predetermined limits. When the pre-set current or voltage limits are exceeded, the contact system trips and the breaker trips.

The electromagnetically operated contact system is based on a metal armature that is suspended in a stationary magnetic field. This armature is attached to a link and push rod assembly that is connected to the main contacts. When the current or voltage limits are exceeded, the armature is drawn into the field, causing the link and push rod assembly to open the circuit breaker contacts.

The breaker also has a range of current and voltage ratings so it can be used for a variety of applications. The breaker can be set to trip on a wide range of current and voltage levels, from low current and voltage of up to 400V and 10A, to high current and voltage of up to 1600V and 200A.

Conclusion

The IELHK21111-1REG4-31246-6 is a versatile circuit breaker that can be used in industrial, commercial and residential settings. This breaker is designed to protect against short circuits, over-current, over-voltage, under-voltage, and overloads. It utilizes an electromagnetically operated contact system that is based on a metal armature that is suspended in a stationary magnetic field. This breaker can be set for a wide range of current and voltage levels, and it is perfect for protecting sensitive loads such as pumps, motors, and industrial machines.
