IULHK11-1-61-30.0-A-01 Application Field and Working Principle

Circuit Breakers are an indispensable element for both residential and commercial environments. They are a protective device against electric shock, used to detect abnormal voltage conditions and then interrupts the current flow. IULHK11-1-61-30.0-A-01 is a type of circuit breaker with wide applications in both indoor and outdoor environments.

This breakers operate by introducing a fault current into a closed circuit, and when the current exceeds a predetermined level, the breaker trips and the current is interrupted preventing further damage to the system. The breaking capacity is determined based on the load, which should not exceed the breaking capacity of the breaker. It also has an adjustable tripping threshold.

Various Applications

IULHK11-1-61-30.0-A-01 circuit breakers are typically used in residential applications, controlling sources such as lighting circuits, heating systems, air conditioning systems and electrical outlets. They can also be used to short-circuit protection for fuses and overload protection for circuit resistance. Furthermore, IULHK11-1-61-30.0-A-01 circuit breakers are also used in medium voltage distribution systems, providing rugged protection from electrical surges and faults.

This type of breaker complies with the performances of the relevant IEC standards and is usually mounted together with the power system. They are commonly employed as overload and short circuit protection devices.

Working Principle

IULHK11-1-61-30.0-A-01 circuit breakers are composed of two sub-assemblies- the frame and the switch. The frame holds all the components together and the switch is responsible for interrupting the current. The frame is divided into two parts: the trip unit and the contact assembly. The contact assembly will open when the trip unit detects an overload or short circuit, interrupting the current. The breaker is reenergized after the fault has been cleared and the contact assembly is closed.

The design of the circuit breaker includes thermal and magnetic elements. The thermal element measures the current flowing through the fault and trips the breaker when a pre-set current limit is reached, while the magnetic element is also known as the instantaneous trip tripping the breaker almost instantly.

The switch also includes a wide range of auxiliary contacts for control and signaling purposes. Relying on the auxiliary contacts, multiple breakers can be connected together for more comprehensive protection. The contact assembly contains the contacts, which will be opened and closed when the breaker trips.

Conclusion

IULHK11-1-61-30.0-A-01 is a reliable and robust circuit breaker with wide applications in residential and industrial scenarios. It has adjustable tripping thresholds, an adjustable rated current, and wide-ranging auxiliary contacts that make it ideal for multiple applications. It carries out the job of circuit protection by tripping the breaker when an abnormality is detected, thus protecting the system from further damage.
