Junction Boxes for Series-Resistance Cables

Junction boxes are designed for connecting of series-resistance heating cables, such as SNF and TMF, to power network.

Boxes’ models are supplied in 2 installation variants:

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

The enclosure design ensures moisture and dust ingress protection IP66 and high corrosion stability. Cable glands of the box are intended 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 installed terminal blocks allow the connection of multi-core or single-core wires with a cross-section of 1.5 to 10 mm² (JB2221-223 models) or up to 16 mm² (JB2221-333, JB2221-533 models). Design options with screw or spring terminal straps are available to order.
