Circuit Breakers

A circuit breaker is an automatic switching device, designed to carry and interrupt current in an electrical circuit. The IULB1-36490-40 is a circuit breaker that is commonly used in a wide range of industrial and residential applications due to its compact size and efficient operation. In this article, we will discuss the application field and working principle of the IULB1-36490-40 circuit breaker.

Application Field

The IULB1-36490-40 circuit breaker is designed to be used in medium voltage applications up to 480 VAC. This circuit breaker is well-suited for industrial and residential applications and can be used in a variety of branch, feeder and main circuit breaker panel points. It can also be used in multiple circuits for a more efficient and safe operation. This circuit breaker is compact and easy to set up, making it suitable for a number of applications. It can be used for the maintenance of both new and existing electrical systems in residential and industrial settings.

Working Principle

The IULB1-36490-40 circuit breaker works on the principle of magnetic current interruption. When the circuit breaker senses an overload or a short circuit, it trips, cutting off the energy supply to the circuit it is protecting. This prevents the circuit from being overloaded or damaged. It works by detecting an overload or short circuit in the circuit and triggering a switch mechanism to trip and break the circuit. This switch mechanism is usually a mechanical device consisting of a coil, an armature and a contact. When the coil is energized, it attracts the armature, which pushes the contact to interrupt the flow of current. The IULB1-36490-40 circuit breaker is designed to detect an overload or a short circuit and trip in milliseconds, which ensures the circuit is protected quickly.

Conclusion

The IULB1-36490-40 circuit breaker is an effective and efficient switching device designed to provide protection against short circuits and overloads in medium voltage electrical circuits. Its compact design and easy setup make it suitable for a variety of applications in industrial and residential settings. This circuit breaker works on a magnetic current interruption principle and trips in milliseconds, ensuring the circuit is protected quickly and efficiently.
