TBB series main line branch terminals are the top choice for connecting main supply conductors.

Their advanced brass body design minimizes costs, while simplified screw mounting shortens installation time.

The halogen-free, self-extinguishing plastic casing enhances safety. Identical designs in the 25 mm² and 35 mm² variants allow effortless stacking and combinations.

The TBB series is compatible with solid, stranded, and flexible copper or aluminum conductors—made possible by a specialized triple coating on the brass body.
