UR-AX - Universal Crossing-Box

Universal crossing-box series UR-AX is designed for making connections of signaling and telecommunication cables in intrinsically safe circuits. Connection between wires in the box are implemented using multipole spring terminals. Cable entries can be made of plastic or metal depending on customer choice. Their number can also vary depending on customer implementation needs. Device is made as intrinsically safe, allowing their use in mining in areas with danger of explosion of methane and / or coal dust.
