BS 408 / 508

Product Description and Application

The BöSha plug-in connector system BS 408/508 is used for the assembly of a complete compact luminaire system (in connection with the coal face and compact light fitting BS 588400) to be applied in potentially explosive atmospheres.

 

They are designed as line plug-in connectors (each plug and socket connected via cable entries with heavy rubber-sheathed cables) and for installation in enclosures of type of explosion protection Ex e ("increased safety").

 

The plug-in connectors consist of plug-in connector plug and plug-in connector socket.

Both enclosure parts, plug and socket, when connected are screwed together with special fasteners according to EN 60079-0.

 

Plug and socket mainly consist of a plastic enclosure, an insulating body and the contact pins and contact bushes with the wiring points which are placed within the insulating body.

 

Characteristics of explosion-proof luminaires with plug-in connector system
• Saving time when installing the luminaires
• For instruction and training no qualified personnel required
• All luminaires including plug and socket
• Pre-assembled luminaire chains also with plug and socket
• Suitable line termination units for the plug connection system (simple troubleshooting)
• Interchangeable system components
