Table 3-35: Vertical installation position
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.
