IEGH66-34487-1-V Circuit Breaker

A circuit breaker is an automated device in an electrical system which is designed to detect a fault condition, such as an overload or short circuit, and to interrupt the flow of current to protect the system from damage. The IEGH66-34487-1-V circuit breaker is an exemplar of modern circuit breakers which are reliable and efficient. This article will provide an overview of the IEGH66-34487-1-V circuit breaker and its application field and working principle.

Application Field

The IEGH66-34487-1-V circuit breaker is designed for use in a variety of applications. Its dimensions, construction, and technology all make it suitable for use in residential, commercial, industrial and utility applications. Its universal characteristics mean that it can be used to replace older, less reliable circuit breakers, while providing superior protection. It can be used to protect motors, large transformers, and even solar inverters, making it an ideal choice for a wide range of applications. It is also ideal for low voltage applications because it offers a wide range of trip settings, allowing it to provide protection without tripping in a faultless condition.

Working Principle

The working principle of the IEGH66-34487-1-V circuit breaker is quite simple. It is based on the use of a thermal bimetal element, which is designed to operate under a resistor-like load and in a normal operating temperature range. This element is designed to detect excessive temperature, then activate its circuit breaker contact, which in turn will break the electrical circuit and protect the load from electrical overload or fault.

When the breaker is triggered, an arc is created between the moving blades. This arc creates an intense heat, which the thermal bimetal element is designed to detect and activate the circuit breaker. The thermal bimetal element is heated by the arc, and when it reaches a certain temperature, it will bend and cause the circuit breaker contact to open (tripping) and breaking the electrical circuit in the process.

The IEGH66-34487-1-V circuit breaker also has two other protective features: a differential current element and a voltage-activated element. The differential current element is designed to detect a fault in the circuit that is causing an excessive rise in current, while the voltage-activated element is designed to detect a fault in the circuit that is causing a drop in voltage. Both these features help to protect the circuit from damage due to overvoltage or undervoltage.

The IEGH66-34487-1-V circuit breaker is also designed to provide superior short-circuit protection. When a short circuit is detected, the breaker will sense the excessive current and break the circuit almost instantaneously, thus providing superior protection against the hazard of short-circuiting.

Conclusion

The IEGH66-34487-1-V circuit breaker is a reliable and efficient device which can be used in a variety of applications. It utilizes a thermal bimetal element and two other protective features to ensure the safe and effective operation of the circuit. By protecting against overload, short-circuiting, and voltage-related hazards, the IEGH66-34487-1-V circuit breaker is an essential addition to any electrical system.
