ITAK Ex (i)

Surge Arrester

ITAK for use in intrinsically safe circuits
  • Prewired unit
  • Built-in arrester, tested to ATEX and FISCO requirements
  • Other customised versions available on request

Description

ITAK stands for the German designation "Informationstechnik-Anschaltkasten" [English: switchbox for information technology systems]. Typically, ITAKs are a combination of enclosure, arresters and terminals or shield terminals. These switchboxes can be tailored to customer needs. Our standard product range includes e.g. ITAK EXI BXT 24, a combination of ALGA 5 X enclosure and BXT BD EX 24 arrester for protecting two intrinsically safe measuring circuits in outdoor areas.
The enclosure is also available without arrester.
