3-pole version<br />
Plug-in in-line disconnectors in 3-pole version are available<br />
<strong>with</strong> single-breaks or double-breaks.<br />
4-pole version<br />
Plug-in in-line disconnectors in 4-pole version always have<br />
double-breaks.<br />
The neutral conductor (4th pole) is factory-fitted as an add-on<br />
module on the 3-pole in-line disconnector.<br />
The neutral conductor is dimensioned for 100 % of the phase<br />
conductors.<br />
The connection on the 4th pole is comprised of a permanently<br />
mounted copper bar. A fuse cannot be installed in place of the<br />
copper bar.<br />
The neutral conductor is connected as the first pole when<br />
switched on and is disconnected as the last pole when<br />
switched off.<br />
The in-line disconnector is completely locked in the ON position.<br />
