X.SA. Control and signalisation boxes

Explosion-proof control and signalling boxes X.SA. in explosion-protected design serve for manual switching of lighting control alternating and direct current circuits, signalling of operating conditions and meaning of electrical values in areas with the risk of explosion of flammable gases, vapours, dusts and explosives – chemical industry, paint shops, gas industry, arms manufacture, 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 it to order.
