Certificate TR EAEU Fireproof junction boxes.pdf The body of junction boxes is made of 3mm thick galvanized steel and is covered by polymeric paint. It has double protection against corrosion because of galvanic treating and polymeric cover. Elements of connections and fittings also have galvanic anti-corrosion cover. Density of contact between the cap and the body is implemented via a silicon pad.
There are ceramic terminal blocks inside the body, which provide a tap screw connection and a grounding grip. The cap of the box is connected with “RE” grip via grounding wire inside the body.
There are special metal glands installed in side walls for cable with 6-12 mm outer diameter. Cable glands are equipped with a intumescent sleeves which frequently grow in size under high temperatures creating solid coked cellular material fixing the cable in such position that prevents an availability of a short current.
It is possible to use cables laid in metal hose, corrugated stainless pipe, pipe for water and gas. You can find types of cable glands used for cable connection laid in a metal hose, corrugated stainless pipe, pipe for water and gas below.
Approved for use within cable lines for provision of electrical operability according to GOST R 53316-2009.
Provide workability under standard temperature conditions according to GOST 30247.0-94 during 120 minutes.
Temperature range: from -40ºС to +100ºС.
It is possible to manufacture boxes with temperature range from -60ºС to +130ºС
Maximum voltage: 450V
Maximum cross-sections in terminal blocks mm2: 3,0; 6,0; 10,0.
Modifications
* Cable glands of other diameter can be installed on customer’s demands if technological capability of such installation is available. In this case, possible quantity of cable glands can differ from values mentioned in the table.
** Without regard to hangers and inputs
Designation of junction boxes during the order
KM-O-О(10k*6,0)-IP66-х A(sq)B(sq)C(sq)D(sq)E(sq)F(sq)G(sq)H(sq)I(sq)J(sq)K(sq)L(sq)M(sq)N(sq)O(sq)P(sq) R(sq)S(sq) T(sq) where:
KM-O – denomination;
10k - number of contacts in a terminal block;
6,0 – maximum possible cross-section of wires connected to terminal blocks. In the case of installation of a terminal block needed for connection wires with a cross-section up to 3,0 mm2 this designation is not used;
IP66- degree of protection;
х - designation of size of a junction box: «100х100»; d; «120х120» (see the table “Modifications” KM-O IP 66). In the case of modification with 80x80mm size designation is not used
A(sq)B(sq)C(sq)D(sq)E(sq)F(sq)G(sq)H(sq)I(sq)J(sq)K(sq)L(sq)M(sq)N(sq)O(sq)P(sq) R(sq)S(sq) T(sq) – placement, availability and type of a cable gland.
Types of cable glands used for connection of the cable laid in a metal hose, corrugated stainless pipe, pipe for water and gas below shall be specified during the order.
Types and manufacturers of cable glands can be changed at the discretion of the manufacturer keeping all the basic properties.
Ordering price of non-standard cable glands and RAL painting are on request.
