Ordering Code:

КВХ1 – Х2 – (Х3/N3) – А (Хa/Na) – В (Xb/Nb) – C (Хc/Nc) – D (Xd/Nd) where,

Enclosure Characteristics:

X1 – enclosure material (c – stainless steel);

           if an enclosure with explosion protection of the "intrinsically safe circuit" type is required

         , the sign "i" should be added, 

Х2 – explosion-proof enclosure index (see Table).

Terminal Characteristics:

Х3   – terminal type (cross-section of the connected conductor),

        if this terminal is used for a grounding wire, the sign "z».

Screw terminals are installed by default. If spring-type terminals are required, index "P" should be added.

Grey terminals are installed by default. If blue terminals are required, index "B" should be added.

N3  – number of terminals of this type;

Cable Gland Characteristics:

А (Хa/Na) – type and quantity of cable glands on side A (top);

В (Xb/Nb) – type and quantity of cable glands on side B (bottom);

C (Хc/Nc) – type and quantity of cable glands on side C (left);

D (Xd/Nd) – type and quantity of cable glands on side D (right).

For example, an explosion-proof stainless steel enclosure (type KVs-14) with external dimensions of 220×120×90 mm, equipped with five terminals for 2.5 mm² conductors, ten terminals for 6 mm² conductors, one grounding terminal for a 4 mm² conductor, one M16 opening at the bottom of the enclosure, and one VVKm32 metal gland for a non-armoured cable installed at the top of the enclosure, is designated as follows:

KVs–14 – (2.5/5, 6/10, 4z/1) – А (VVKm32/1) – V (M16/1).
