Phoenix Contact 3064027 To ensure safe operation, disconnect the terminal block first and verify that the maximum load current does not exceed the total current of all connected conductors. Current and voltage are determined by the type of plug used, with a nominal voltage of 500V. The thermal continuous current rating is 20A and requires a screw connection method. The rated cross-section for the cable is between 0.14mm2 to 6mm2, depending on the specific size required. It should be mounted using NS 35/7.5 or NS 35/15 fittings in gray color.
