Mechanical Interlocking
Mechanical interlocking depends on interlocking shaft rotation (refer to figures 28 to 32). The mechanical interface
for the connection of mechanical interlocking is placed at the ISM frame between the terminal blocks XT1, XT2
(refer to figure 35). There is a slot on the visible face of the interlocking shaft. If the slot is directed vertically the
module is in “unlatched” position. If the slot is directed horizontally the module is in “open and locked” position.
A handle connected directly to interlocking shaft via mating part is recommended. This handle shall be freely rotated
up to 90 degrees in both directions. The handle operated by fingers shall be dimensioned so as to provide rotating
force in accordance with local standards.
Possible tasks of the mechanical interlocking:
· Prevents operation of the disconnectors when switching module is closed (stationary type of switchboard)
· Prevents operation of the truck isolating mechanism when switching module is closed (draw out type)
Design of mechanical interlocking (by example of a draw out unit, figures 33, 34).

Interlocking shaft is unlatched.
ISM can be opened and closed.

Interlocking shaft is in locked
position at opened ISM.
