Components for customer assembly
Assembly kits with wiring modules and mechanical connectors
are available for contactor assemblies for wye-delta starting.
Contactors, overload relays, function modules for wye-delta
starting, auxiliary switches for electrical interlock – if required
also infeed terminals – must be ordered separately.
The wiring kits for sizes S00 and S0 contain the top and bottom
main conducting path connections between the line and delta
contactors (top) and between the delta and star contactors
(bottom).
Selection of contactors for customer assembly
For contactors, see page 5/19.
1)
When using the function modules for wye-delta starting,
the wiring modules included in the assembly kit for the auxiliary
current are not required.
2)
Version in size S0 with spring-type terminals:
Only the wiring modules for the main circuit are included.
No connectors are included for the auxiliary and control circuit.
