Phoenix Contact 3210198 To ensure safe operation, disconnect the terminal block and verify that the total current of all connected conductors does not exceed the maximum load current. The current and voltage values are determined by the type of plug used, with a nominal voltage of 400V and a thermal continuous current rating of 20A. For push-in connections, the rated cross-section ranges from 0.14mm2 to 4mm2, and mounting options include NS35/7.5 and NS35/15, with a standard color of gray.
