When designing and selecting air circuit breakers, the main technical indicators that should be assessed are as follows. These technical indicators play a vital role in ensuring the safety and efficiency of the electrical system where air circuit breakers are installed.
First, the voltage rating of the air circuit breaker is a key consideration. The ACB should be compatible with the voltage requirements of the electrical system. The rated voltage range is AC200 to 690V and DC250 to 400V, so the rated voltage of the air circuit breaker must match the system voltage.
Another important technical indicator is the rated current (Inm) of the low-voltage circuit breaker frame. Different brand ranges have different rated current levels and it is important to carefully review the product’s technical information to ensure it meets the requirements of the electrical system.
The current rating (In) of the low voltage circuit breaker is also a key consideration. The selection should be based on the designed transformer capacity (kV·A) and detailed analysis of the technical data of the required product.
Rated operating breaking capacity (Ics) is a key indicator of air circuit breaker performance and reliability. It is important to select a product with the appropriate breaking capacity based on load levels, construction type and financial considerations.
In addition, the rated ultimate breaking capacity (Icu), rated short-time withstand current (Icw), number of poles, etc. are all important technical indicators that should be evaluated when selecting an air circuit breaker.
When reviewing these specifications, it is important to consider the specific requirements and characteristics of the electrical system in which the air circuit breaker is installed. By carefully evaluating these specifications, an air circuit breaker can be selected to suit the needs of your electrical system, ensuring safety, reliability and optimal performance.
