Circuit Breakers

The IELHK111-1-72-30.0-01-V is a type of circuit breaker which is designed for building switchboards, cabinets and electrical distribution systems. It is one below within the internationally recognized IELHK range of circuit breakers. This type of circuit breaker is known for its simplicity and has a wealth of features that make it suitable for a number of applications.

Circuit breakers are designed to protect circuits from overloads or short circuits and are at the heart of all electrical, actuator, and process control systems. This type of circuit breaker detects any undesired events and is able to reserve the circuit by interrupting current flow. It is commonly used to protect end-users from the risks associated with fault currents, as well as to isolate power supplies in circuit faults.

IELHK111-1-72-30.0-01-V Application Field

This type of circuit breaker is mainly used in building switchboards and electrical cabinets. Its main purpose is to protect people, assets, materials, and critical equipment and assets from electrical hazards. Its robustness and robust construction makes it suitable for a variety of industrial purposes. It may be used in places such as manufacturing lines, warehouses, and data centers.

It can be installed in buildings with normal, moderate and extreme environments and is able to withstand the stresses caused by short circuit currents. In addition to this, it can be used in electric motor control centers, motor drive control panels, and other industrial electrical applications. It is suitable for all types of alternating currents, from 1kV to 690V.

IELHK111-1-72-30.0-01-V Working Principle

The circuit breaker works by detecting any electric fault and cutting off the power supply immediately. This type of circuit breaker has a built-in thermal unit that acts as the main breaker. When the current load exceeds a certain threshold, the thermal unit triggers a contact to open, automatically cutting off the flow of electricity. Once this happens, it has to be manually reset in order to restore power.

Furthermore, these circuit breakers are also equipped with a trip unit that detects any fault and automatically trips the breaker. This trip unit is an integrated part of the circuit breaker and can detect a variety of faults, including those related to short circuits, overloads, and ground faults. This ensures that the IELHK111-1-72-30.0-01-V circuit breaker is highly reliable.

Conclusion

The IELHK111-1-72-30.0-01-V is a very reliable circuit breaker and is used in a variety of applications. It is mainly used in building switchboards and cabinets for protection against short circuits and overloads. Its thermal protection and trip unit make it highly reliable, and its robustness makes it suitable for industrial uses. Overall, the IELHK111-1-72-30.0-01-V circuit breaker is extremely reliable and can provide quality protection in any electrical application.
