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:
