X.X. Terminal boxes

Explosion-proof increased safety X.X. terminal boxes (Ex e) according to the specific design, are used for connection and branching of cables of heavy and light current distribution, I&C circuits and intrinsically safe circuits (Type XX / JB) in areas with the risk of explosion of combustible gases, vapours, dust and explosives - chemical industry, paint shops, gas industry, etc.

They are manufactured in several standard variants (especially polyester boxes) divided by usage.

If you do not find the desired box amongst them, we will produce the box to order.

Type key:

X (1) X (2) /JB
X Design X - explosion-proof
L - industrial
1 Dimension type list of all dimensional types can be found below or in catalogue sheet
X Marking
Terminal box
2 Box material
0 - Al alloy
1 - polyester
2 - stainless steel sheet
/JB Intrinsically safe /JB - marking only for intrinsically safe versions

Example of order code: X20X1 (explosion-proof terminal box) or X20X1/JB (explosion-proof intrinsically safe terminal box) or L20X1 (industrial terminal box)

Do not forget to add quantity and type of terminal, cable glands to possible order.
If you are not sure about the size of the box, we will design it according to specific filling.
Empty boxes (Ex components) can be found here.
