The stations are intended for switching and indicating the operating mode of AC and DC electric circuits of industrial frequency in hazardous areas.The stations are marked with explosion protection "1Ex d IIB T6 Gb" and can be used in explosive zones of class 1 and 2 according to GOST IEC 60079-10-1-2011.Body material - aluminum alloy.
The post contains up to three switching elements (button, switch) or indication (LED lamp).The types of elements are specified when ordering.Posts can have plates with operational inscriptions in Russian and foreign languages: "Start", "Stop", etc.The posts are designed for connecting armored and non-armored electric cables of circular cross-section, as well as cables in a metal hose or pipe.
Posts are supplied with cable glands of various designs:
- for open laying of cables with a diameter of 10-18mm;
- for laying a cable with a diameter of 10-14 mm in a pipe with an attached thread G1 / 2;
- for laying a cable with a diameter of 10-18 mm in a pipe with an attached thread G3 / 4;
- for inserting armored cables with a through-hole diameter of 10-18 mm and an outer diameter of up to 25 mm;
- for connecting cables up to 18mm in diameter in metal hose RZTsKh-20, 25, 32mm.The thread of all cable entries is pipe G3 / 4.
