Baumann CONTACT ELEMENTS Advantages

COMPARISON WITH CONTACT LAMELLA

Contact lamellas are used in high-voltage and medium-voltage applications as well as in other industries. Similar to BAUMANN Contact Elements, contact lamella is a groove connection: a groove in the piston or the housing of the assembly accommodates the contact. BAUMANN Contact Elements have successfully replaced lamella contacts in, for example, 3-position switches, earthing switches, busbar-connections, EPUs, disconnector switches, plug-in tech, panel coupling and cable ends.


BAUMANN Contact Elements have the following advantages compared with contact lamellas:


  • Large conductor tolerance
    Thanks to their spring characteristics, BAUMANN Contact Elements compensate for a conductor tolerance of IT7 to IT8 (compared with IT4 to IT6 of substitute products). A wide range of tolerances reduces the manufacturing cost of the piston and the housing.

  • Simple groove design
    The groove that accommodates BAUMANN Contact Elements in the piston or housing has a simple triangular shape. The simple groove shape reduces manufacturing costs and allows an efficient plating process (e.g. silver plating).

  • Convenient and efficient assembly
    The diameter of BAUMANN Contact Elements can be slightly compressed or expanded during assembly. Its assembly does not require any tools. Therefore, assembly line managers prefer BAUMANN Contact Elements because a convenient and efficient assembly reduces lead times.

  • Long product life cycle
    BAUMANN Contact Elements cause less abrasion to the piston and are well suited for dynamic applications. Our customers use BAUMANN Contact Elements in applications with 10,000 cycles and 30 years of maintenance-free life.
