IEG6-36489-30-V application field and working principle

Circuit breakers are essential devices in our electrical infrastructure, protecting electrical power supplies from damage due to short-circuits, surges and overloads. With the advancement of technology, circuit breakers have become increasingly intelligent, with additional features such as protection from single-pole switching. One such example is the IEG6-36489-30-V series of circuit breakers.

Applications of the IEG6-36489-30-V Circuit Breaker

The IEG6-36489-30-V series of circuit breakers are designed primarily for variable frequency drives and motor drives. The circuit breaker is designed to provide protection against both overload and short-circuit conditions. It is suitable for a wide range of applications, such as pumping systems, industrial motors, production lines and other associated electrical loads.

The IEG6-36489-30-V series of circuit breakers have increased safety features which enable them to protect against harmonic loads, reducing the likelihood of harmonic-related issues. The circuit breaker can also provide additional protection from single-pole switching, a type of short-circuit that occurs when only one phase of an alternating current is switched off.

The IEG6-36489-30-V series of circuit breakers also has a built-in service switch, which provides manual control for the circuit breaker - allowing the user to control the operations of the circuit breaker with ease. The service switch can also be remotely operated, providing further flexibility.

The Working Principle of the IEG6-36489-30-V Circuit Breaker

The IEG6-36489-30-V series of circuit breakers operate using an electromechanical system. The circuit breaker is designed to detect any increasing overload or short-circuit in the current flow and trip the breaker to interrupt the circuit. This is done by detecting a high level of applied current and utilizing a trip unit which triggers the circuit breaker to interrupt the current flow.

The IEG6-36489-30-V series of circuit breakers utilize a thermal-magnetic operating principle, with two separate mechanisms for detecting a fault in the electrical circuit. The first is the thermal element, which detects the expected rise in temperature caused by an increasing current flow, while the second element is the magnetic element which measures the increasing current, triggering the circuit breaker when a predetermined level of current is reached.

The IEG6-36489-30-V series of circuit breakers also utilize an electrical tandem mechanism, which enables the circuit breaker to detect lower levels of current. This is an additional safety feature which can help prevent circuit damage due to lower levels of current.

Conclusion

The IEG6-36489-30-V series of circuit breakers are designed for use in variable frequency drives and motor drives, providing increased safety features to protect against overload and short-circuit conditions. The circuit breaker utilizes an electromechanical system, which utilizes both a thermal and a magnetic element to detect a fault in the electrical circuit and interrupt the current flow. The IEG6-36489-30-V series of circuit breakers also features a built-in service switch for added convenience and flexibility in operation.
