A connection and distribution system that<br />
brings convenience and versatility to lighting<br />
installations. The range consists of 80mm a modular dia.<br />
plug and socket interface which provides electrical<br />
connection in one easy click-in action. Luminaries<br />
can be plugged in without isolating the circuit.<br />
All live contacts are inaccessible and the earthing<br />
connection is made before any other.<br />
Wired products incorporate either heat resisting<br />
(WHR) or low smoke zero halogen (LSF) insulated 86mm<br />
75mm dia.<br />
and sheathed flexible 0.75mm four core circular<br />
cable.<br />

Features<br />
● Live contacts are inaccessible<br />
● Earth Contact – first to make, last to<br />
break<br />
● Mechanical and <strong>Electric</strong>al Connection in<br />
