Control box for Ex-zones

Ysebaert NV has an extensive range of empty enclosures that we can equip with terminals, relays, PLCs, electronic switches, circuit breakers, control components and cable glands at your request. The internal wiring of the control box must always be installed by Ysebaert NV. These control boxes are available in pure Ex d or combined Ex d e versions. Ex t (= dust) is also possible. When using metallic glands on a plastic enclosure, we earth them using an internal brass earthing plate.

Certification of control box

If you choose the Ex d solution, standard industrial components can be built in. It should be noted that Ex d enclosures are suitable for gas group IIB(+H2) using a flange with bolts as a flame path while Ex d enclosures suitable for gas group IIC have a screw cover. An added advantage is that we can provide your Ex d enclosures with a round or rectangular window (display) upon request. If you choose the Ex d e solution, all the internal components must each have their own ‘component certificate’.
