Introduction to IEL2-31303-1-V

Circuit breakers are designed to protect electrical circuits from overloads and short circuits. They operate with either mechanical or electronic controls, allowing system designers to choose the best architecture for the application. IEL2-31303-1-V is a thermal-magnetic (TT) circuit-breaker which is the optimal choice for home and industrial applications due to its unique features. This circuit breaker offers reliable over-temperature protection, precise over-current protection, and selectable tripping curves.

Applications for IEL2-31303-1-V

The IEL2-31303-1-V is ideal for use in residential and commercial applications such as protection from overloads and short circuits. This circuit breaker is also used in industrial applications such as medical, communication, robotics and data-processing networks, as well as lighting and HVAC systems. It is designed to automatically de-energize, when a fault occurs, to reduce the risk of equipment damage or fire.

Working Principle of the IEL2-31303-1-V

The IEL2-31303-1-V circuit breaker has two distinct elements – the thermal element and the magnetic element. The thermal element can be used in conjunction with a temperature-dependent device, to protect against sustained overloads or short circuits that cause excessive current and heat buildup in the circuit. This element uses a bimetallic strip, which bends when heated and trips the breaker when the current exceeds a certain threshold.The magnetic element of the IEL2-31303-1-V is sensitive to the instantaneous overcurrent and provides a more precise protection capability. Upon tripping, this element releases a trip solenoid which operates an internal switch that disconnects the circuit. It can also be used in combination with the thermal element to provide additional protection.The IEL2-31303-1-V also offers selectable tripping curves, which allow the user to set custom tripping thresholds according to the specific application. This feature can be used to provide more responsive and effective over-temperature protection in cases where the current might vary significantly.

Conclusion

The IEL2-31303-1-V is an efficient, reliable and robust thermal-magnetic circuit breaker for residential, commercial and industrial applications. The thermal element and the magnetic element offer precise and effective protection from over-currents and over-temperature conditions, while the selectable tripping curves provide greater flexibility. By using this circuit breaker, the risk of equipment damage or even fire due to overloads and short-circuits is minimized.
