Circuit Breakers

Circuit breakers are electrical devices designed to protect electrical circuits from damages caused by excess current, short circuits, and overvoltage. They are used to quickly disconnect an electrical circuit when an overload, short circuit, or other type of abnormal situation causes more current to flow than the circuit can handle. This is done by opening the circuit at a predetermined current level and preventing further current from flowing. The IEG66-27797-3-V circuit breaker is designed to protect circuits from damage due to over-current and overvoltage.

IEG66-27797-3-V Application Field

The IEG66-27797-3-V circuit breaker is designed for electrical equipment and applications that require high reliability and safety, such as home appliances, equipment for industrial use, computers, communication equipment, power transformers, and motor control equipment. The circuit breaker is designed to guard against abnormal power supply situations, such as voltage spikes, power sags, and power outages. It can also act as an emergency shutoff in case of an emergency or over-current situation as it is designed to open quickly when the current reaches a certain threshold.

IEG66-27797-3-V Working Principle

The IEG66-27797-3-V circuit breaker is composed of two parts: an electro-mechanical tripping mechanism and an electromagnetic tripping mechanism. When current flows through the circuit breaker, the load is connected to an electromagnet which creates a magnetic field. When the current through the circuit exceeds the maximum threshold, the magnetic field will cause the contacts of the circuit breaker to open the circuit, interrupting the flow of current and preventing further damage to the circuit. Additionally, for overvoltage protection, an additional voltage sensitive relay is used to detect a dangerous increase in voltage and trigger the circuit breaker to open the circuit.

Conclusion

The IEG66-27797-3-V circuit breaker is designed to protect electrical circuits from damages caused by excess current, short circuits, and overvoltage. It is used in a variety of applications, including home appliances, motors, and communication equipment. The circuit breaker is composed of two parts: an electro-mechanical tripping mechanism and an electromagnetic tripping mechanism, and also a voltage sensitive relay for overvoltage protection. The IEG66-27797-3-V circuit breaker is designed to open quickly when the current reaches a certain threshold and prevent further damage to the circuit.
