Ex-Empty Enclosures MULTI-BOX Ex empty enclosures made of aluminium are conform to all requirements for installation sectors where explosive concentrations of gases, steams and dusts can appear (zones 1 and 2 as well as 21 and 22). MBA-Ex-enclosures have a components certificate confirming constructive security to the mechanical component ‘enclosure’. Thus, the enclosure specific parameter does not have to be retested and reapproved when registering a new Ex-product which simplifies the approval process considerably. After installing approved electrical and electrotechnical components into...

MULTI-BOX Ex e-junction boxes are conform to all requirements for installation sectors where explosive concentrations of gases, steams and dusts can appear (zones 1 and 2 as well as 21 and 22). MBA-Exe-enclosures can be used in the temperature classes T4 up to T6. Temperature class 6 signifies that – even in case of the maximum assembly of terminals – the maximum temperature does not exceed 85°C neither inside nor outside the enclosure. Thus, combustible gases, steams and dusts cannot be fired. By the exterior earthing, the enclosures are included in the potential compensation. This...

Ex-Enclosures Multi-Box Overview & Information MULTI-BOX Ex i-junction boxes are conform to all requirements for installation sectors where explosive concentrations of gases, steams and dusts can appear (zones 1 and as well as 21 and 22). MBA-Ex i-enclosures can be used in the temperature classes T4 up to T6. The explosion protection of so-called intrinsically safe enclosures « i » is based upon the low voltage and electricity connected in the enclosure (e.g. data or telephone lines). Thanks to the limit of ignition energy, the occurrence of a spark is absolutely impossible. Even rising the...
