Explosion-Proof Linear Luminaire - Aluminium/Plastic

Back to Overview

2 x 18 to 3 x 58 Watt

Product Description and Application

BöSha linear luminaires provide uniform light, even under the toughest ambient conditions. Not only in Ex areas, but everywhere where humidity and dust prevail, increased fire protection regulations have to be complied with and breakage safety is required these luminaires, being applied for the illumination of long routes, ensure operational safety and reliability.


Typical application areas can be found in the chemical and petrochemical industry, in mines, shipyards, tank systems, food processing facilities, production halls and warehouses, underground car parks, and much more.


The new explosion-proof linear luminaires of the BS 5*****, BS 9***** and BS 8***** series, for bi-pin and four-pin fluorescent lamps, meet the requirements of the ATEX Directive 94/9/EC.


State-of-the-art, economical ballasts, in connection with bi-pin fluorescent lamps, contribute to achieving a luminous efficiency which is 30 % higher compared with conventional ballasts and Fa6 fluorescent lamps. By standard unilateral through wiring, in connection with an easily accessible terminal compartment, the installation work is reduced.


Additional time saving during the installation is achieved by applying the optionally available, pre-assembled ready for operation plug connection system BS 208***.
