Multi-Ex MBA Ex-Empty Enclosure from The Enclosure Company

MULTI-BOX Aluminium-Ex empty enclosures made of aluminium are conform to all requirements for installation fields where explosive concentrations of gases, steams and dusts can appear (zones 1 and 2 as well as 21 and 22).

MBA-Ex empty 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 the enclosure, the complete unit has to be retested followed by a proof of heating.

Multi-Ex Explosion Proofed MBA Ex-e

Multi-Ex Explosion Proofed MBA Ex-e Enclosure from The Enclosure Company

MULTI-BOX Aluminium-Ex e junction boxes are conform to all requirements for installation fields where explosive concentrations of gases, steams and dusts can appear (zones 1 and 2 as well as 21 and 22). MBA-Ex e enclosures can be used in the temperature classes T4 up to T6. Temperature class 6 signifies that, even in case of warming the assembly of terminals, the maximum total temperature does not exceed 85C 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 completely avoids electrostatic charging and sparks resulting from it. If the premises permit, the Ex-junction boxes of protection type increased safety e can be combined with intrinsically safe i power circuits. The minimum clearance and creepage distance between the terminals of both power circuits must then be 50 mm. Even in this case there is no heating of the intrinsically safe power circuit.

Multi-Ex Explosion Proofed MBA Ex-i

Multi-Ex Explosion Proofed MBA Ex-i Enclosure from The Enclosure Company

MULTI-BOX Aluminium-Ex i junction boxes are conform to all requirements for installation fields 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 temperature or heating our Ex i-junction boxes assembled with the maximum amount of series terminals cannot cause any explosion. By the exterior earthing, the enclosures are included in the potential compensation. This completely avoids electrostatic charging and sparks resulting from it. In order to make visible an intrinsically safe power circuit when installing Ex i-enclosures, once has to choose blue or blue marked cable glands and blue terminals.
