Introduction

Circuit breakers, commonly referred to as CBs, are devices used to protect electrical systems from over-currents, short circuits and other types of dangerous conditions. CBs are considered a vital component in the modern electrical systems and are used in every electrical application from personal computers to large nuclear power plants. The IEGF6-34542-20B-V is a device specifically designed for use in industrial applications and can be used to protect critical electrical components from potentially disastrous consequences. This article explores the application field and working principle of this device in order to understand its purpose and capabilities.

Application Field

The IEGF6-34542-20B-V is a medium-sized circuit breaker designed specifically for use in industrial applications. It has been designed to cope with short circuit current levels of up to 10 kA and is suitable for use with AC systems up to 690 V. Therefore, it is suitable for most industrial power requirements such as motor control centres and switchboards. It has been tested to UL489 and CSA C22.2 and complies with these standards. The device is also rated for Class II locations meaning it can be used in hazardous or explosive environments.

Working Principle

The IEGF6-34542-20B-V circuit breaker works by monitoring the current flowing through the circuit. If the current levels exceed the designed maximum, the breaker will trip and disconnect the circuit. This occurs in two stages, a “slow trip” and a “fast trip”. The slow trip stage is triggered when the current increases significantly. This causes the breaker to make contact and start the delaying action. The delay gives the circuit time to react and prevent a full trip. If the circuit responds correctly, the breaker will return to its normal state after the delay period is over. If the current continues to increase, the breaker will activate the fast trip stage and trip the circuit completely. This is done to protect the circuit from potential damage.

Conclusion

The IEGF6-34542-20B-V circuit breaker is designed specifically for use in industrial applications. It is rated to cope with short circuit current levels of up to 10 kA and is suitable for use with AC systems up to 690V. It works by monitoring the current flowing through the circuit and will trip if the levels exceed the designed maximum. This offers a protection system that prevents potential damage to the circuit in the event of over-currents or short circuits. The device is also rated for Class II locations, meaning it can be used in hazardous and explosive environments.
