Motor and auxiliary contacts (including the contactor relay variants) are
included in frame size S00.
Installation in series
No derating is necessary up to an ambient temperature of 60 °C for all the
contactors, even those in side-by-side installation.
In the case of contactors with an extended operating range (0.7 to 1.25 x U
s
)
that use a series resistor, installation in series is permissible up to an ambi-
ent temperature of +70 °C.
3.5.2 Connection
The SIRIUS contactors are available with the following terminal types:
• Frame sizes S00 to S3: screw-type terminals
• Contactors and auxiliary contactors of frame size S00: All the terminals
are also available as Cage Clamp terminals
• Contactors of frame sizes S0 to S3: The auxiliary switches and coil con-
nections are also available with Cage Clamp terminals.
• Accessories: screw-type and (for most of the range) Cage Clamp termi-
nals
• The contactors of frame size S3 have removable box terminals for the
main conductor terminals. This enables the connection of ring lugs or bus-
bars.
