These barriers are flexible insulated partitions used to
reinforce isolation of connection points in installations
with busbars, whether insulated or not.
Barriers are installed vertically between front or rear
connection terminals.
They are mandatory for voltages
u
500 V for both fixed
and withdrawable products and for L and LB types,
whatever the voltage.

contact cluster when the device is in the disconnected
or test positions (degree of protection IP20). When the
device is removed from its chassis, no live parts are
accessible.
The shutters can be padlocked (padlock not supplied)
