Junction box РТВ 601-1Б/3П ССТ 2226249

RTB 601 junction box is designed for connecting self-regulating electric heating cables to the power grid, as well as for branching self-regulating heating cables. The box also allows for branching the power cable to create engineering networks. The box comes equipped with an inlet device for thermal insulation and is mounted directly onto the surface of a pipeline or tank. The box allows for the connection of up to four self-regulating electric heating cables. The housing design provides IP66 protection against moisture and dust ingress and high corrosion resistance. The cable entries of the box are designed for connecting unarmored power cables with a diameter of 7 to 18 mm or armored power cables with a diameter of 12 to 20 mm. The applicable terminal sets allow for the connection of multi-strand or single-strand wires with a cross-section of 1.5 to 10 mm2. Versions of the boxes with screw or spring terminal clamps are available for order. Heating cables connected from the point of exit from the box to the point of entry under thermal insulation can be additionally protected by a mechanical protection device, which is available in a version based on PVC-insulated flexible metal conduit (RSh) or based on corrugated steel pipe (RS). When equipping the junction box with a mechanical protection device, special cable entries are additionally included in the box to enable connection.
