IEC 61439 norm: Digital solution facilitates thermal calculation of switchgear

Excessive heat: An absolute fear of control cabinet builders. Because only if the systems are resistant to heat are they safe and can be operated without hesitation. But calculating heat in accordance with standards is a major challenge for plant engineers. For example, different variables such as power loss, temperature resistance or cable lengths have to be taken into account, which come from different component manufacturers. However, the required values are often not found in the corresponding material databases and have to be determined manually in the end. Systematised calculation tools offer an efficient and legally secure solution here.
