It comes in a grey colour and has a nominal current rating of Cu 425 A and Al 380 A, as well as a nominal insulation voltage of 600 V. This terminal block is suitable for use with both copper and aluminium cables. The tin plating on the block prevents galvanic reactions. It features an internal barrier that allows for the connection of aluminium and copper cables to a single block. The screw head size is 8 mm, making it easy to mount on panels.
