The distance between two consecutive connection plates on the 04456 is 64 / 65mm:
Each connection plate is prepared for the connection of maximum 8 cables (4 on each face of a connector plate).
It's the responsibility of the panel builder and sub-contractor to check creepage distance and more specifically clearance distance of connections on the connector plates: see IEC61439-1, for Ui =1000V the clearance distance must be greater or equal to 14 mm.
