Thanks to the visibly clear distinction between switching positions and extremely small enclosure with 4 integrated terminals, the isolator terminal is very easy to install. The labelling options are the same as for rail-mounted terminals. The MODEX isolator terminal is installed directly in an Ex e enclosure and installed in the same way as a rail-mounted terminal. As a terminal with positive opening operation, it offers additional safety. All live parts are protected against accidental contact which allows you to open the Ex e enclosure and to operate the switch by hand when voltage is applied and within the explosive area. Connected actuators or sensors have 2-pole activation and can thus be replaced under potentially explosive conditions.
