Thermistor motor protection relays
Ordering details - PTC temperature sensors C011

Description1SVC 110 000 F0531

The PTC temperature sensors (temperature-dependent with positive temperature coefficient)
are selected by the manufacturer of the motor depending on:
– the motor insulation class according to IEC/EN 60034-11,

2 – the special characteristics of the motor, such as the conductor cross-section of the wind-

ings, the permissible overload factor etc.
– special conditions prescribed by the user, such as the permissible ambient temperature,

risks resulting from locked rotor, extent of permitted overload etc.
One temperature sensor must be embedded in each phase winding. For instance, in case of
Temperature sensor characteristics three-phase squirrel cage motors, three sensors are embedded in the stator windings. For
pole-changing motors with one winding (Dahlander connection), 3 sensors are also sufficient.
Pole-changing motors with two windings, however, require The sensors are suitable for em-
RPTC bedding in motor windings with rated operating voltages of 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
104 overvoltage. Due to their characteristics, the thermistor motor protection relays can also be
used with PTC temperature sensors of other manufacturers which comply with DIN 44 081
103 and DIN 44 082 6 sensors.
If an additional warning is required before the motor is switched off, separate sensors for a
correspondingly lower temperature must be embedded in the winding. They have to be con-

nected to a second control unit.
