3RA13, 3RA14 Contactor Assemblies
3RA13 Reversing Contactor Assemblies
3RA13 complete units, 3 ... 45 kW
■
Overview
The 3RA13 reversing contactor assemblies can be ordered as
follows:
Sizes S00 to S3
• Fully wired and tested, with mechanical and electrical
interlock (for voltages > 500 V, a dead interval of 50 ms on
reversing must be taken into account)
Sizes S00 to S12
• As components for customer assembly.
Complete units
The fully wired reversing contactor assemblies are suitable for
use in any climate. They are finger-safe according to EN 50274.
The contactor assemblies consist of 2 contactors with the same
power, with one NC contact in the basic unit. The contactors are
mechanically and electrically interlocked (NC contact interlock).
For motor protection, either 3RU11 overload relays for direct
mounting or individual mounting or thermistor motor protection
tripping units must be ordered separately.
Components for customer assembly
Installation kits for all sizes are available for customer assembly
of reversing contactor assemblies.
Contactors, overload relays, the mechanical interlock (as of size
S0) and – for momentary-contact operation – auxiliary switch
blocks for latching must be ordered separately.

There is also a range of accessories (auxiliary switch blocks,
surge suppressors, etc.) that must be ordered separately.
For overload relays for motor protection, see "SIRIUS Overload
Relays".
The 3RA13 contactor assemblies have screw connections and
are suitable for screwing or snapping onto 35 mm standard
mounting rails.
