The TRANBERG® TEF 1058 marshalling box distributes local field power to several heat tracing circuits or other consumers from one Ex eb enclosure in stainless steel AISI 316L. It is built on the TEF 1058 heat trace junction box, developed and manufactured at the R. STAHL Tranberg factory in Stavanger, and delivered with ten terminals linked in two groups of five, an earth bar, entries with temporary plugs and a stainless steel label kit, so only cable glands need to be added. Up to five heating cables of up to 64 W/m can be connected.
