Constantly changing demands, but also changing technology and export guidelines are well-known challenges for a machine- and panel builder. An ever-increasing response time is the enduring trend and process optimization a requirement. Therefore, the time is really over to manually keep track of things around an electro-technical design in an excel sheet. The time and stress that this takes and the chance of errors that such a method entails, no longer fits in a world that is changing ever faster and is becoming more digital. After all, what machine or panel builder doesn't want to be able to select the right switching and protection devices for a motor or load at the push of a button, including required cable diameters and short-circuit calculations?
