MULTI-BOX MBP-Ex e junction boxes made of reinforced polyester meet all the requirements for facilities where explosive concentrations of gases, vapors and dust can occur (zones 1 and 2, as well as 21 and 22).
MBP-Ex e enclosures can be used for temperature classes T5 to T6.
Temperature class 6 means that even if the contact assembly is heated, the maximum total temperature will not exceed 85 ° C either inside or outside this case. Thus, combustible gases, vapors and dust are not flammable. The graphite additives in the polyester material prevent static charge on the surface of the casing with the help of low surface resistance = lt; 10 * 9 Ohm.
If standards permit, explosion-proof junction boxes of increased degree of protection with the marking “e” can be combined with intrinsically safe power circuits marked “i”. The minimum clearance and creepage distance between the contacts of both power circuits can then be 50 mm. Even in this case, no heating of intrinsically safe power circuits occurs.
