Every ATEX / IECEx marking starts with an “Ex” plus a letter: d, e, i, p, n. Those letters tell you how the equipment prevents ignition. Flameproof Ex d contains an explosion, Ex i removes

There are two protection levels Ex eb and Ex ec for Zones 1 and 2 respectively, older equipment will just be labelled Ex e covering both Ex eb and Ex ec.

The Ex e protection concept involves reducing the likelihood of ignition sources (e.g., temperature, sparks, electric arcs) occurring on both the device''s enclosure surface and inside it.

An instrument junction box is an enclosure housing terminals that allows interconnection between field devices (i.e. instruments, switches etc) in the process/production areas, and control or monitoring

There are not many devices made solely with increased safety, we could give the example of a junction box with relative Ex-e connection terminals (see Figure 1) or an asynchronous motor with squirrel

The optimised design, like the circumferential protection channel on the cover opening and the silicone seal suitable for the most extreme temperature ranges, makes the enclosures usable worldwide.
