Ex-e Connection and Bus-Bar Boxes

Connection and bus-bar boxes for GHG 64

Regardless of whether for offshore applications or for use in harsh environments found in chemical plants and refineries: thanks to the optimised selection of materials, combined with a high quality powder coating (> 100 µm) and the use of stainless fixing materials, the new flameproof light alloy enclosures of the series. GHG 64 with flat flamepaths can be used in all areas. The modular design, the wider temperature range (-55 °C to +55 °C) and the compact design are further highlights of this product range.

A time-saving installation method

The time-proven Ex-e connection and bus-bar boxes are a meaningful addition to the GHG 64 range of enclosures. With these, the easy and safe realization of complex connections and current strengths of up to 630 A is standard.

Depending on customer requirements, these connection / busbar boxes, that have been adapted in an optimal way to the modular system of the flameproof enclosures, are available in stainless steel and powder-coated sheet steel and in 11 different sizes and can, therefore, be used in variable ways for a wide variety of enclosure combinations.

The various circuits of the distribution can be connected quickly and economically using a bus-bar system. Currents up to 1150 A are possible.According to your requirements, individually encapsulated devices, such as control and indicator units, e.g. as pushbutton, control switches or Ex-e measuring instruments and Ex-i digital indicating instruments can also be built into the Ex-e connection and bus-bar boxes.

  • Ex-e enclosures that have been adapted to the modular system
  • Busbar boxes in both Ex-e and Ex-d design
