Assembly kits for con-
tactor combinations
The following accessories are components of the self-assembly kits and
they are described in the diagrams of the relevant kit:
• side mount mechanical interlock
• Mechanical connectors
• Wiring modules
Assembly kits for
reversing combinations
The following table shows you the components of the kit for the contactor
combination for reversing in frame size S00 and explains how to put it
together:
Electrical interlock Note
Contactors with an NC contact in the basic unit (3RT101.) are required for
the electrical interlock.
Drawing: frame size S00 Step Procedure
1/2/3 Mount the mechanical inter-
lock between the two contac-
tors.
4/5 Press the two connecting clips
from above and below onto
the two contactors.
6 Attach the wiring modules to
connect the main conducting
paths and to electrically inter-
lock the two contactors
(3RT10.1). Make sure that the
wiring modules are flush with
the contactor at the side.
