Warum ein Schütz manchmal K und manchmal Q heißt

#ElectricalEngineering #DIN81346 #CircuitDiagram In this video, we'll look at the identification letters according to DIN EN IEC 81346-2 using typical practical examples. Based on realistic scenarios such as relays, impulse relays, motor controllers, and indicator lights, I'll explain why equipment is no longer identified by its device type, but rather by its function within the system. You'll learn, among other things: why a relay is designated with the letter K when Q is used for switching devices in the energy flow why a light fixture can be marked with E and how to understand identification letters in circuit diagrams more quickly Perfect for electronics apprentices, mechatronics engineers, and anyone who wants to learn how to read circuit diagrams.
