Phoenix Contact 3210193 To ensure safe connections, first disconnect the terminal block to prevent any electrical shock or damage. The maximum allowed load current must not exceed the total current of all connected conductors, which is determined by the type and voltage rating of the plug being used, with a nominal voltage of 400V and a nominal current of 16A. The connection method is typically a push-in connection, while the rated cross-section can vary from 0.14mm² to 4mm² depending on the specific requirements. Additionally, mounting options include NS35/7.5 and NS35/15, and all conductors should be protected with a gray color code.
