Distribution Boxes BS 63-17

Product Description and Application
The distribution boxes BS 63*/*/17****, together with cable entries and terminals, serve for the connection of conductors of cables and leads of intrinsically safe circuits. After inserting and/or attaching additional components they can be used as control and signal equipment - in which case further certified auxiliary components, like light emitting diodes e. g., may be installed as well.
 
Standard sizes available in many gradations (l x w) from 150 x 150 mm to 1200 x 800 mm ; other sizes, too, are easily available as special designs.
