The control, monitoring and distribution boards in ‘Ex de’ execution of the EJBE series, in aluminium and stainless steel, and the EJBXE series, in stainless steel, were designed to meet specific installation requirements in environments with an explosion risk. In fact they allow you to install electric components such as switches, inverters, fuses, relays, etc. in ‘Ex d’ enclosures to develop the control, monitoring and signalling units, housing the auxiliary terminal block in intrinsically safe ‘Ex e’ enclosures. EJBE control boards consist of an ‘Ex d’ enclosure of the EJB series, in aluminium alloy, and an ‘Ex e’ enclosure of the CTB series in stainless steel. Whereas EJBXE control boards consist of an ‘Ex d’ enclosure of the EJBX series and an ‘Ex e’ enclosure of the CTB series in stainless steel. This fully stainless steel structure is suitable for especially difficult environments, such as marine environments, which require greater protection against corrosion. ‘Ex d’ enclosures are mechanically linked to ‘Ex e’ enclosures by means of a flange and electrically linked by Cortem TP sealed bushings in nickel plated brass or in stainless steel. The number and diameter of the sealed bushings varies depending on the size of the enclosures and the number and cross-section of the cables. The IP protection between two enclosures is guaranteed by a flat silicone gasket resistant to acids, to hydrocarbons and to high and low temperatures. The lids of the ‘Ex d’ enclosures can be supplied with a tempered glass window to see and monitor the electric equipment inside.
