Reversing Contactor Assemb. for SIRIUS 3RT1 Contactors, up to 250 kW

More information

Home page, see http://www.siemens.com/sirius

 


The individual parts for the reversing contactor assemblies for customer assembly must be ordered separately.

  • For 3RT contactors (see "Power Contactors for Switching Motors" > "SIRIUS 3RT Contactors, 3-Pole up to 250 kW")
    The operating times of the individual 3RT10 contactors are rated in such a way that no overlapping of the contact making and the arcing time between two contactors can occur on reversing, providing they are interlocked by way of their auxiliary switches (NC contact interlock) and the mechanical interlock.
    For assemblies with AC operation and 50/60 Hz, a dead interval of 50 ms must be provided when used with voltages over 500 V; a dead interval of 30 ms is recommended for use with voltages up to and including 400 V. These dead times do not apply to assemblies with DC operation. The operating times of the individual contactors are not affected by the mechanical interlock.
  • For the mechanical interlock, see "Accessories and Spare Parts" > "for SIRIUS 3RT1 Contactors and SIRIUS 3RH1 Contactor Relays" > “Miscellaneous")
  • For wiring kits consisting of link rails (see "Accessories and Spare Parts" > "for SIRIUS 3RT1 Contactors and SIRIUS 3RH1 Contactor Relays" > “Miscellaneous")
  • For the base plate, see "Accessories and Spare Parts" > "for SIRIUS 3RT1 Contactors and SIRIUS 3RH1 Contactor Relays" > “Miscellaneous":

Further components

  • For momentary-contact operation: auxiliary switch (NO contact) for self-locking
  • 3RB2 overload relays (see "Protection Devices"), SIMOCODE pro 3UF7 motor management and control devices (see "Monitoring and Control Devices") or 3RN thermistor motor protection evaluation devices (see "Monitoring and Control Devices" > "Relays") can be used as overload protection.
