Interlocked sockets are equipped with an
integrated isolator switch AC3-AC23A which guarantee;
Load break disconnect on nominal rated current.
Safe Isolation in the OFF position.
10,000 switching cycles at full load
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The plug cannot then be withdrawn until the isolator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.
