Things to know about terminal enclosures

A terminal enclosure is used to house electrical connections and built-in components. It enables the protected and safe integration of electrical components in machines and systems.

Terminal enclosures are used in various industrial applications. Typical areas of application are

  • Mechanical and plant engineering
  • Automation technology
  • Energy and infrastructure projects
  • Outdoor areas exposed to the elements
  • Railway technology and applications with special approvals

The choice of material has a direct influence on how an enclosure behaves in use. Aluminium is particularly suitable for applications with high mechanical loads. Plastic variants such as polyester, ABS or polycarbonate, on the other hand, offer advantages in terms of moisture or corrosive influences as well as low weight.

BERNSTEIN offers terminal enclosures in precisely these materials, reliably covering the requirements of typical industrial applications.

In outdoor areas, enclosures must be permanently protected against moisture, dust and temperature fluctuations. Suitable materials and protection classes such as IP66 or IP67 are crucial here.

For applications under such conditions, special versions are used that are designed for outdoor use.

Additional requirements apply in potentially explosive atmospheres. Here, Ex terminal enclosures are used that fulfil the relevant standards and approvals such as ATEX and guarantee safe operation.

The selection of a suitable terminal enclosure always depends on the specific application. The ambient conditions, the mechanical load and the material and protection class requirements are particularly important.

Standards and approvals can also play a role, for example in outdoor applications or in potentially explosive atmospheres. Careful coordination ensures that the enclosure functions reliably in the long term and can be integrated without the need for additional customisation.
