Plug-In Connectors (increased safety)Back to Overview
BS 408 / 508
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
