16www.se.comStraight lengths constitute the basic structure of the line and are made up of:1 an all-in-one carrier casing, crimp closed, forming a rigid beam made of sheet steel, in RAL 9003 white lacquered sheet steel, hot galvanised on both sides. This casing also acts as the protective earth conductor (PE),2 a ribbon cable with two or four copper conductors, 3 one, two, three or five connector outlets,4 an electrical jointing unit ensuring automatic and simultaneous connection of all live conductors,5 a mechanical joining device made of galvanised sheet steel that makes the connection of two lengths rigid and resistant to bending. The degree of protection is IP55 (without accessories).The busbar trunking is non-flame-propagating as per the recommendations of standard IEC 60332-3. All the insulating and plastic materials are halogen-free and have enhanced fire-withstand capabilities (incandescent wire test as per standard IEC 60695-2). b960°C for components in contact with live parts. b650°C for other components.Multi-circuit possibilitiesThe many possibilities offered by KBB trunking means specialised circuits can be created, e.g. for emergency lighting, presence detection, dimming.One circuitTwo circuitsStandard offer without bus L1NPEL2L1L3NPEPEL1NL1NL2L1L3NL1NPEL2L1L3NL2L1L3NPEStandard offer DALI bus is made by using two regular conductorsDali +Dali -LNPEL2L1L3NDali +Dali -PEStandard offer with internal shielded bus and dedicated connectors supporting KNX protocol.
