Ratings of three-phase motors

The quoted rating (in kW) refers to the output power on the motor shaft (according to the nameplate).

The power rating specifications of the contactors in kW (in accordance with IEC 60947-4-1, Table G) are guide values for 4-pole standard motors at 50 Hz AC and specified voltage (e.g. 400 V AC). The actual starting and rated data of the motor to be switched must be considered when selecting the units. The motor current, motor protection device and the permissible contactor current according to the utilization category must be aligned with each other.

Operating mechanism types

3RT1 contactors

The following control and/or operating mechanism versions are available in sizes S6 to S12:

• Standard operating mechanism with economy circuit for AC and DC operation (switchover from closing coil to holding coil)
• Solid-state operating mechanism
  Overvoltage damping of the operating mechanism coil is already integrated in the electronics for contactors with solid state operating mechanisms. The operating mechanisms are powered via a supply voltage with an operating range from 0.8 to 1.1 x Us, optionally also controlled depending on the chosen mode of operation. Alternatively, control is also possible via the separate 24 V DC control signal input. Various rated voltage ranges for AC/DC control are available.
  
  The following versions are available:
  • With two operating modes: Direct control or via CPU input
  • As above, but with additional remaining lifetime indicator (RLT)
  • With fail-safe PLC input for simplification of safety applications (without mode of operation selection)
