Product Datasheet

Application Areas

Approved for installation in explosion hazard areas

Designed for connecting self-regulating electrical heating cables to the power network and for the branching of self-regulating heating cables*.

Box models are supplied in 2 installation variants:

  • complete with a pipe installation stand UVK for direct mounting onto the surface of a pipeline or tank;
  • for installation onto the wall, onto a nearby metal structure or using a bracket directly onto the pipeline (brackets supplied separately).

The enclosure design ensures moisture and dust ingress protection IP66 and high corrosion stability. Cable gland of the box is intended for connecting unarmoured power cables with a diameter of 7 to 18 mm or armored power cables with a diameter of 12 to 20 mm.

The installed terminal blocks allow the connection of multi-core or single-core wires with a cross-section of 1.5 to 10 mm2. Design options with screw or spring terminal straps are available to order.

*This junction box is compatible with self-regulating heating cables HTM, HTA, HTP, BTC, BTX, HTB, CTE.
