Introduction

Circuit breakers are electrical devices that are used to protect against sudden power overloads and short circuits in electrical systems. The IULNK112-37035-3 is a circuit breaker made by the Italian manufacturer IULNK, and is designed for use in industrial environments. This article will discuss the application field and working principle of the IULNK112-37035-3.

Application Field

The IULNK112-37035-3 is a low-voltage circuit breaker, which means it is designed for use with access circuits or end-of-line protection in industrial applications. It is particularly suitable for use in low-voltage distribution systems, and can be used for electric motors, pumps, compressors, and other consumer loads. It is also suitable for environments with a moderate degree of humidity and corrosive pollution conditions.

Working Principle

The IULNK112-37035-3 has a three-pole circuit breaker, which means there are three different circuits inside the device that are each capable of carrying the electrical current. The device works by using two contactors to sense the current in each circuit and to disconnect the power supply if it becomes too high.The contactors are separated from each other by a bridge rectifier, which helps convert the alternating current to direct current. The bridge rectifier also helps prevent back-flow of electricity, as it can act as a one-way gate. If the current in one of the circuits reaches its maximum level, the contactors will disconnect the power supply to the circuit, protecting the device from overload.The IULNK112-37035-3 is equipped with a switch-off timer, which is an additional safety precaution. This timer ensures that if the device has been on for a certain period of time, it will automatically switch off, preventing the possibility of damage due to overheating.

Conclusion

The IULNK112-37035-3 is an excellent choice for use in low-voltage industrial settings and has proven to be reliable in its functions. Its three-pole circuit breaker, contactors, bridge rectifier, and switch-off timer all work together to provide efficient and safe protection from power overloads and short circuits.
