Interlocking of two or three toggle-controlled devices
Two devices can be interlocked using this system. Two identical interlocking systems
can be used to interlock three devices installed side by side, in which case one
device is in the ON position and the two others are in the OFF position. Devices must
all have the same conguration, i.e. xed, plug-in, withdrawable or drawout.
The system is locked using one or two padlocks (shackle diameter 5 to 8 mm).
Two interlocking system models are available for:
Compact NS100 to 250
Compact NS400 to 630.
