Circuit Breakers have become a critical component in almost all electrical systems. They are designed to interrupt current in the event of an over-current or short-circuit situation. IEG1-21478-2 is one such device which is used in many applications. This article will provide an overview of its application field and working principle.

Application Field

IEG1-21478-2 is a type of circuit breaker typically used in the high performance equipment of industrial machines. When the current exceeds the normal operating range, IEG1-21478-2 will instantly operate and break the circuit, thus preventing harm to the equipment and users. It is used in a wide range of applications such as automotive, electromechanical and energy systems. It can also be used in motor-driven systems, safety devices, HVAC systems and fire safety systems. IEG1-21478-2 is also suitable for many large-scale and high-power motor controls.

Working Principle

IEG1-21478-2 uses a thermal or magnetic actuation technique for operation. When an overload or short-circuit situation arises, the device triggers and opens the circuit. This interruption of current prevents the system from experiencing severe damage due to the increased current. In thermal operated breakers, the time required to trip the breaker depends on the amount of heat generated by the elevated current. Conversely, magnetic operated circuit breakers are equipped with a trip solenoid which is actuated by a magnet when the current rises. Both types of breakers function similarly in that they trip regardless of the direction of current flow.

In addition to thermal and magnetic trips, IEG1-21478-2 is also equipped with an arc quenching system. This is an integral component which helps to limit the arc generated by the breaker as it opens. Further, IEG1-21478-2 includes an internal overload trip, which senses the current in the circuit and disconnects to interrupt the power flow. This limits the impact of the current on the system. The device also includes indicators to illustrate when it is tripped and the direction the current is running for quick visual inspection.

IEG1-21478-2 is a highly reliable circuit breaker which has been used in many industrial and commercial applications. Its thermal or magnetic actuation and internal overload trips allow it to quickly interrupt the current even in the event of an extreme overload or short-circuit situation. Its arc quenching capability and indicators further ensure user safety and convenience. IEG1-21478-2 is suitable for many high-current applications where reliability and safety are of paramount importance.
