Introduction

The IEL111-1RS4-29094-1-V is a circuit breaker used in a variety of applications to protect electrical equipment from excessive current or temperatures. It is designed to open the circuits when the current or temperature exceeds a predetermined amount. This helps to prevent damage to electrical equipment from things such as overloads or short circuits.

Application Field

The IEL111-1RS4-29094-1-V Circuit Breaker is primarily used in industrial and commercial applications such as in factories, power plants, and other large-scale systems. They are also used in residential applications like protecting the circuits in a home from power surges or overloads. It is important to note that the effective current and temperature protection is only provided with the correct installation and setup of the breaker.

Working Principle

The IEL111-1RS4-29094-1-V has a thermal-magnetic design, meaning it uses both thermal and magnetic protection to open a circuit when conditions exceed the predetermined thresholds. The thermal element of the breaker is a thermal bimetal element that will open the circuit when the temperature reaches a predetermined setting due to an overcurrent condition. The magnetic element is a trip coil that will detect the amount of current through the breaker; when it exceeds the predetermined amount, it will pull in an armature which causes the breaker to open the circuit.

When the breaker detects either a high temperature or an excessive current, it will open the circuit, thus breaking the connection and stopping the flow of electricity. Once the temperature or current has decreased and is within the proper range, the breaker can be reset and the circuit can be reconnected.

Conclusion

The IEL111-1RS4-29094-1-V Circuit Breaker is an effective and reliable circuit breaker that is used in a variety of applications, from industrial and commercial to residential. It is designed to open a circuit when the current or temperature exceeds a predetermined amount, helping to protect electrical equipment from damage. The breaker uses a thermal bimetal and trip coil to detect these conditions, and can be easily reset once the conditions have returned to normal.
