IULNK1-32388-4 application field and working principle

Circuit breakers are electrical switches that protect electrical circuits from being overloaded or shorted out. The IULNK1-32388-4 is a type of circuit breaker that is used in many applications due to its high current carrying capacity and low voltage rating.

The IULNK1-32388-4 circuit breaker is rated for circuits with a maximum current of 1500 amps. This circuit breaker also has an operating voltage of 500 Volts and an interrupting rating of 50 kA (kilo-amps). It also has a maximum contact gap of 7.5 mm, making it suitable for use in many applications.

The IULNK1-32388-4 circuit breaker has a wide range of applications. It is commonly used in residential, commercial, and industrial settings. In residential applications, it is often used to protect high-load circuits, such as air conditioners and stove outlets. In commercial applications, it is often used to protect LED lighting circuits and motion sensing lighting circuits. In industrial applications, it is commonly used to protect motors and large machinery.

Working Principle

The IULNK1-32388-4 circuit breaker utilizes two sets of contacts, an on/off switch, and a trip curve or thermal overload curve. When the current is low, the on/off switch remains closed and enables the current to flow. Once the current reaches a predetermined level, the trip curve is triggered and the breaker trips open, disconnecting the circuit.

The thermal overload curve is used to protect against currents that are greater than the rated value of the breaker. If the current rises beyond the rated value, the thermal overload curve trips and the circuit is disconnected. The trip is also designed to reset after the current drops below the rated value.

In addition to its on/off and trip capabilities, the IULNK1-32388-4 circuit breaker also has a ground-fault detector. This detector can sense when there is a difference in the magnitude of the current in the line and the current in the neutral conductor. If the difference is too great, it will trip and disconnect the circuit.

Conclusion

The IULNK1-32388-4 circuit breaker is a high-capacity, low voltage circuit breaker that is commonly used in many applications. It has an operating voltage of 500 volts, a current rating of 1500 amps, and an interrupting rating of 50 kA. It is used to protect circuits from overloads and ground-faults. The on/off switch enables the current to flow, and the trip curve protects the circuit from overloads. The thermal overload curve is also used to protect the circuit from currents that are greater than the rated value.
