Approvals

Junction boxes JB2221-544-2X(11-59) are designed for power distribution during installation, repair and upgrade of power cables and utility networks in explosion hazard areas.

The box is mounted onto a nearby metal structure. The box allows connection of up to six power cables.

The enclosure design ensures moisture and dust ingress protection IP66 and high corrosion stability.

The box has following cable glands:

  • up to two glands for unarmored cable with a diameter of 14 to 25 mm or armored cable with a diameter of 17 to 26.3 mm (for models JB2221-544-21(11-38)) or armoured cable with a diameter of 23.5 to 33.6 mm (for models JB2221-544-21(39-59)).
  • up to four glands for unarmored cable with a diameter of 7 to 18 mm or armored cable 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 2.5 to 35 mm2.

  • Efficient solution for power supply cables connection in electrical heating systems
  • All required component parts included in the scope of supply
  • Wide application range
  • Quick and easy installation
  • High thermal stability
  • Non-corrosive
