High-current brush holders

Rugged graphite brushes for high currents

We use so-called high-current brush holders for lightning protection and transferring earthing currents from static to rotating components.

With the different configurations including even encased designs combined with other MR products (see SEA), users can choose from a large selection covering all sorts of applications. Currents in excess of 1,000A have already been transferred in hybrid rotary distributors with these products! And even 64,000A has been achieved for electroplating plants at the request of a customer.
