Circuit breakers are safety devices that protect electrical systems from damage by switching them off in the event of an overload or short circuit. The IEG6666-35996-3-V circuit breaker is an example of an efficient and dependable circuit breaker. This article will discuss the application field and the working principle of the IEG6666-35996-3-V.

Application Field

The IEG6666-35996-3-V is a medium-voltage circuit breaker specifically designed for use in outdoor switchgear installations. It has a rated voltage of 690V AC, a rated frequency of 50Hz, and a rated current of 3100A. The breaker is suitable for use in public and industrial power distribution systems, or any other locations where a circuit breaker is needed.

Working Principle

The IEG6666-35996-3-V is a shielded, three-pole circuit breaker. This means that it is capable of isolating one or more circuits from electrical power in the event of an overload or short circuit. The breaker also has an adjustable trip setting. The trip setting can be adjusted to trip the breaker when current exceeds a predetermined limit. This feature helps to ensure that the circuit breaker can protect devices and wiring from damage due to overloading.

The IEG6666-35996-3-V circuit breaker utilizes a two-step arc extinguishing process to quickly break the circuit. This process involves using a spring-loaded element to create an arc and separate the contact points of the breaker. The arc chamber then utilizes a quenching gas to extinguish the arc, which then allows the contact points to come together and close the circuit.

Conclusion

The IEG6666-35996-3-V is an efficient and dependable medium-voltage circuit breaker specifically designed for use in outdoor switchgear installations. It has a rated voltage of 690V AC, a rated frequency of 50Hz, and a rated current of 3100A. The breaker utilizes a two-step arc-extinguishing process to quickly break the circuit and can also be adjusted to trip the breaker when current exceeds a predetermined limit. This makes it an excellent choice for use in public and industrial power distribution systems.
