All the T series junction boxes are UV-resistant. They are made of polypropylene (a thermoplastic polymer) and are equipped with strain relief entries and pre-terminated Wieland connection sockets, type GST-18-i3 (s = black, w = white, r = red). The strain relief entries can be penetrated directly with the cables. The special structure of the opening means that the cables cannot be removed unintentionally. Suitable for cable diameters of between 7 and 21 mm.
The junction boxes can be mounted on mounting plates in the openings on the floor using steel bolts 3.5 x 9.5. Cover with labelling panel and lead seal.
According to standard VDE 0620-1: Installation only by people with the relevant electrical knowledge and experience. There is danger to life if installed incorrectly.
