OBO FireBox
Safety for cable connections

Cable junction boxes for maintaining electrical functional integrity according to DIN 4102 Part 12
The OBO FireBox, made from Duroplast, intended for the extending or diverting of the functional integrity cable, completes the OBO functional integrity system for safetyrelevant units. The tested and approved types B 100 E, B 160 E and B 250 E will fulfil your requirements reliably and safely. Everything that is needed for assembly is included in the contents of the delivery: the cable junction boxes, four plug-in seals and the connecting unit with two anchor bolts. A unique highlight of the OBO FireBox is the fully pre-assembled connecting unit that is built to withstand high temperatures. As always, OBO has all the solutions for your needs – and all from a single source.

Simply fixed
Mark, drill, screw – and without the need for Rawlplugs. That's how quickly and simply it works with the two preassembled anchor bolts on the connecting unit that also hold the cable junction boxes. To assemble you will need a T30 screwdriver.

Simply installed
The openings through which the cables are to be led are very easily pushed through. The mostly rigid functional integrity cables are to be led into the sealing clamps in the box. Only the larger openings are approved for the functional integrity cables. (Dimensions of the opening: B 100 (E 4 x 32 mm; B 160 E 4 x 40 mm; B 250 E 8 x 40 mm).

Simply safe
The direct connection of the protective earth conductor to the green and yellow screw terminal ensures protection from electric shock in case of touch voltage from the metal parts.

Simply fast
With just a few simple assembly steps one can extend or divert the electrical functional integrity. To finish the job it only remains to affix the filled-out identification label – and one more element of the fireproof cable system is ready and in accordance with DIN.
