          Ordering details - PTC temperature sensors C011



                                    The PTC temperature sensors (temperature-dependent with positive temperature
                                    coefficient) are selected by the manufacturer of the motor depending on:
                              1SVC 110 000 F0531  •   the motor insulation class according to IEC/EN 60034-11,
                                    •   the special characteristics of the motor, such as the conductor cross-section of the
                                     windings, the permissible overload factor etc.
                                    •   special conditions prescribed by the user, such as the permissible ambient temperature,
          Temperature sensor characteristics
                                     risks resulting from locked rotor, extent of permitted overload etc.
                                    One temperature sensor must be embedded in each phase winding. For instance, in case
          RPTC                      of three-phase squirrel cage motors, three sensors are embedded in the stator windings.

          10 4                      For pole-changing motors with one winding (Dahlander connection), 3 sensors are also
                                    sufficient. Pole-changing motors with two windings, however, require 6 sensors. If an
                                    additional warning is required before the motor is switched off, separate sensors for a
          10 3
                                    correspondingly lower temperature must be embedded in the winding. They have to be
                                    connected to a second control unit.
          10 2                      The sensors are suitable for embedding in motor windings with rated operating voltages of

          10 1       TPTC [°C]      up to 600 V AC. Conductor length: 500 mm per sensor.  A 14 V varistor can be connected in
                                    parallel to protect the sensors from overvoltage. Due to their characteristics, the thermistor
