  Standards

  IEC 60947-1, DIN EN 60947-1,

  IEC 60947-4-1, DIN EN 60947-4-1,

  IEC 60947-5-1, EN 60947-5-1 (auxiliary switches)

  The contactors are suitable for use in any climate. They are finger-safe according to IEC 60529.

  3RT contactors: 4 contactors are used for switching resistive loads (AC-1) or as contactors, for example for variable-speed operating mechanisms that normally only have to carry the current.

  The accessories and spare parts for the 3RT contactors can also be used here; see "Accessories and spare parts" → "for SIRIUS 3RT2 Contactors and SIRIUS 3RH2 Auxiliary Switches".

  For a general description of sizes S3 to S12 of 3RT contactors, see "Power contactors for switching motors" → "SIRIUS 3RT contactors, 3-pole up to 250 kW".

  Size S3: AC or AC/DC operation

  • Coil circuits (varistors, diodes, etc.) retrofittable
  • Auxiliary switches can be retrofitted
  • Main and control conductors: Screw terminals

  Sizes S6 to S12: AC/DC operating mechanism (50/60 Hz AC and DC)

  • withdrawable coils with integrated coil switch (varistor)
  • Auxiliary and control conductors: Screw terminals
  • Main conductors: busbar connections

  Operating mechanism types

  Two types of solenoid operation are available:

  • Conventional operating mechanisms
  • Solid-state operating mechanism
    • The operating mechanism for the contactors features solid-state control of the contactor coil. Overvoltage damping of the operating mechanism coil is already integrated in the electronics. The operating mechanisms are powered via a supply voltage with an operating range of 0.7 to 1.25 x U_s, optionally also controlled depending on the chosen mode of operation. Alternatively, control is via the separate 24 V DC control signal input. Various rated voltage ranges for AC/DC control are available.
    • This version is additionally available with a 24 V DC PLC relay output and a remaining lifetime indicator (RLT).
