Terminal bridging

PTR realizes terminal bridging in two different ways. External bridging is realized via the non-insulated (BR) or insulated (BRI) bridging elements that are used as accessories for various types of terminal blocks and that are simply inserted into the wire entry, where they are fastened in place by a screw or spring.

We recommend the AK350-BR or AK700-BR series for the realization of a potential across multiple poles. These two products integrate an internal conductive metal element that passes all the way through, thus also allowing for a wire connection in the clamp area.
