Circuit breakers are an integral part of any electrical system. They protect against circuit overload and short-circuit, and provide safety and convenience when an unexpected or dangerous situation occurs. The IULNK111-1REC4-61-5.00-E circuit breaker is a type of protection device designed for medium-voltage distribution system applications. In this article, we will discuss its application field and working principle.

Application Field for IULNK111-1REC4-61-5.00-E Circuit Breaker

The IULNK111-1REC4-61-5.00-E circuit breaker is a three-pole, air-insulated and oil-immersed metal-enclosed device suitable for indoor installations. It is designed for use in the medium-voltage distribution system for switching in and out of apparatus. It can also be used in other medium-voltage systems such as power plants, factories, and other industrial applications.

The IULNK111-1REC4-61-5.00-E circuit breaker has an interrupting rating of up to 60kA, making it suitable for applications with higher fault levels. It also has a range of standard features such as automatic sensing, thermal overload protection and control, current and voltage limiting, and latching. This makes it a reliable and cost-effective protection device for a range of applications.

Working Principle of IULNK111-1REC4-61-5.00-E Circuit Breaker

The IULNK111-1REC4-61-5.00-E circuit breaker works by interrupting the flow of current to the circuit when the current exceeds the maximum specified rating. It does this by using a series of components such as a trip coil, contact spring, and a trip release mechanism.

The trip coil is used to detect when the current has reached the specified level, and then the contact spring is used to quickly and securely open the circuit. When the contacts open, the arc generated during the operation is quenched by the oil-immersed tank. The trip release mechanism then locks the contacts in the open position until they are reset manually.

The IULNK111-1REC4-61-5.00-E circuit breaker also has a range of additional features that provide additional protection to the user. These include thermal overload protection, current and voltage limiting, and latching. This provides safety during unexpected electrical events.

Conclusion

The IULNK111-1REC4-61-5.00-E circuit breaker is a reliable protection device that is suitable for use in a range of medium-voltage distribution system applications. It works by interrupting the flow of current when the current exceeds the specified maximum, and also offers additional safety features such as thermal overload protection, current and voltage limiting, and latching. This makes it a reliable and cost-effective protection device for any medium-voltage system.
