Terminal boxes are intended for connection and branching of armored and unarmored cables with enclosure of round cross section with copper or aluminum
cores in AC and DC circuits of electrical installations of chemical, gas, oil and other industries, as well as mines and pits being gas and dust hazardous.
The possibility to install clamps for various currents.
Box material can be chosen according to your needs and demands: stainless steel or steel with corrosion-resistant coating.
Six overall dimensions of terminal box.
The terminal box consists of the body and cover forming explosionproof enclosure. Cable glands are located on side walls. Terminal clamps are located
inside the box on mounting plate. Design of terminal box provides availability of external and internal grounding bolts.
P – index indicating use of spring clamps. When using screw clamps, index is not
Х5 – index indicating availability of grounding terminals or grounding buses. If grounding terminals shall be installed, index “РЕ” is indicated, if
grounding buses are installed, index “РЕ bus" shall be indicated for uninsulated one, “РЕ insulated bus" shall be indicated for insulated one. If grounding terminals and buses
are not installed, index shall not be indicated
Х5.1 – index indicating the following:
for grounding terminals upon availability of
several cores being different by cross section area – nominal current, power clamps, with the same cross section. If grounding terminals are the same by cross section as power
clamps, index shall not be indicated
for grounding buses – number of screw clamps on bus (8 or 14)
Х5.2 – index indicating the
for grounding terminals – number of terminals
for grounding buses – number of buses and if necessary,
Х6 – type of cable gland or plug or drainage facility
Х7 – number of cable glands or plugs or drainage facilities
Х8 – side for installation of cable glands or plug or drainage facility (А, В, С, D)
