Phoenix Contact 3038448 To ensure safe operation, disconnect the terminal block as it is not designed to handle loads exceeding the total current of all connected conductors. The maximum load current must be determined based on the plug used, which dictates both the nominal voltage and current rating, set at 400V and 20A respectively with a spring-cage connection method being specified. Furthermore, the cross section area of the conductor is limited to between 0.08 mm2 and 4 mm2, while mounting hardware options include NS35/7.5 and NS35/15 with gray colour coding.
