Norstat now offers the MPB-Ex i Junction Box, a unique enclosure that conforms to all installation field requirements where explosive concentrations of gases and dusts can appear. The enclosure protection of this intrinsically safe enclosure from Multi-Box GmbH is based on the low voltage connections in the enclosure, e.g. data or telephone lines. Thanks to the very small amount of ignition energy and temperature rise, the Ex-i junction boxes can be assembled with the maximum number of terminals without any complications. The graphite additive in the polyester material prevents static charge of the housing surface by the low surface resistance. This completely avoids electrostatic charging and sparks resulting from it.
The MPB-Ex i Junction Box utilize Polyester GRP for both the base and cover with silicone sealing material and stainless steel V2 A screws. These boxes are halogen free as well as being UV resistant. They are approved for Zones 1 and 2 as well as 21 and 22 and with temperature classes T5 to T6. They have a protection rating of IP66 and a flame retardancy rating of V0.
