Terminal Al/Cu, 50-240 Al/10-95 Cu SM4.21

The SM 4.21 clamp is used to connect an aluminum conductor not subjected to mechanical stress with copper conductors. The upper part of the clamp is divided so that two copper conductors of different diameters can be branched from the aluminum conductor. The clamp is cleaned and secured with contact paste. It is clamped with two M10 screws.
