Design and options

PE connectors are stacks of copper strips 0.1, 0.2, 0.3, 0.5 or 1 mm thick, press-welded together without any added material, which gives them very good conductivity; the standard table covers widths of 20–160 mm and cross-sections of 100–3,200 mm².

Material: individual copper strips (laminations)
Joining: special press-welding process, no external materials added

Questions about PE

What current do PE connectors carry?

From 377 to 4,722 A DC according to the catalogue table, from PE 20 (B 20 mm, 100 mm²) to PE 163 (B 160 mm, 3,200 mm²). For AC the table gives 354 to 4,439 A. The calculation conditions are the same as for the PG table.

How is a PE connector built?

From many copper strips 0.1, 0.2, 0.3, 0.5 or 1 mm thick, press-welded together in a special process without any external material. This gives the connector very good conductivity. The ends can be silver-, tin- or nickel-plated.

Can PE connectors be used in high-voltage areas?

Yes. According to the catalogue, the durable and solid construction allows PE connectors to be used even in high-voltage areas, including inside machines.

How do PE connectors differ from riveted connectors?

In how the strips are joined. In PE the strips are press-welded without added material. In riveted connectors, 0.1–0.3 mm strips are riveted under a press and the contacts are reinforced with thicker plates; IZAR makes them only to the customer’s drawing.
