The Interlocked sockets are equipped with rear panel
isolator switches AC3-AC23A which guarantees;
Load break disconnect at nominal current
Insulation in OFF position, thanks to safe distances between contacts
10,000 switching cycles at full load
Prevention - all control gear windows are fitted with
locking device to avoid unauthorized access.
All interlocked sockets can be locked both at position 0 and 1.

Interlocked sockets are equipped with an integral switch
ensuring safe electrical disconnection and isolation.
In order to prevent disconnection of the plug and socket
coupling under load, it is not possible to turn the integral
isolator switch to the ‘on’ position until a mating plug has
been fully inserted.

The plug cannot then be withdrawn until
the isolator has been selected to the ‘off’ position.
It is possible to padlock the isolation switch in both the on
and off positions.
