2DIREKT A Two Wire Power Supply Terminal Clamp, L-Shape

The 2DIREKT A version allows cables to be connected to busbars. The clamp is mounted directly on the busbar. Fine grooves on the underside of the clamp make line contact, ensuring very good power transmission that remains stable over time with minimal contact resistance. Depending on the installation situation, 2DIREKT A is available with a through hole, threaded hole or stud bolt.
