Circuit breakers are vital components used in many electrical systems to protect other equipment from being damaged due to overloads or ground faults. The IALK1-1-51-10.0-AV-01 is such a circuit breaker designed for medium-voltage power systems. Its application field and working principle will be discussed in the following sections.

Application Field

The IALK1-1-51-10.0-AV-01 medium-voltage circuit breaker is suited for indoor installation in secondary distributing switchgears. The minimum system voltage is 3.6kV and up to 10.5kV. The short-circuit breaking capacity is 100kA, including making capacity of 70/65kA, breaking capacity of 80/65kA, and peak current of 100kA. The IALK1-1-51-10.0-AV-01 offers both series ratings and load break switch ratings, making it suitable for use in demanding applications such as arc-furnace protection and protection against cable overloading. Additionally, the IALK1-1-51-10.0-AV-01 has a cabinet that accommodates 17 model types, allowing for easy customization. This feature eliminates the need for external accessories and makes it a cost-effective solution for many applications.

Working Principle

The working principle of the IALK1-1-51-10.0-AV-01 is based on the principle of an arcing contact. This contact is composed of two solid pieces connected to the moving contact of the circuit breaker that are enclosed in an inert gas-filled enclosure. When the contact is opened, an arc forms between the two pieces. The arc is extinguished through the diffusion of the inert gas. This allows the circuit breaker to stop the current flow quickly and safely. In addition, the IALK1-1-51-10.0-AV-01 features an integrated overcurrent and undervoltage protection system. This system is designed to detect any abnormal current and voltage conditions and to take corrective action if necessary.

The IALK1-1-51-10.0-AV-01 circuit breaker is a reliable and cost-effective solution for many medium-voltage power applications. It is aided by an integrated protection system that helps protect other equipment from damage due to overloads or ground faults. Its arcing contact design ensures quick and safe current break and reclosure and makes it an ideal solution for many installations.
