Aluminum junction box / increased safety / in-line / with cable gland

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 thateven in case of warming the assembly of terminalsthe maximum total 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 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.
