2 PTC temperature sensors. The PTC tem-perature sensors are incorporated in the Motor windings to measure the Motor heating. This enables direct control and evaluation of the follow-ing operating conditions: heavy duty starting increased switching frequency single-phase operation high ambient temperature insufficient cooling break operation unbalanceThe relay is independent of the rated Motor current, the insulation class and the method of starting. The PTC sensors are connected in series to the terminals Ta and Tb (or Ta and Tbx without short-circuit detection). The number of possible PTC sensors per measuring circuit is limited by the sum of the individual PTC sensor resistances: RG = R1 + R2 + RN m kq. Under normal operating conditions the resistance is below the response threshold. If only one of the PTC resistors heats up excessively, the output relay de-energizes.

3 If the autoreset function is configured, the output relay energizes automatically after cooling with manual (pushbutton on front-side) or remote reset configuration have to be controlled via the control input by the required applications:Temperature monitoring of equipment with PTC sensors integrated, such as machine rolling bearings, hot-air ventilators, oil, air, heating installations, characteristic for one single temperature sensor acc. to DIN 44 081.

For instance, in case of three-phase squirrel cage motors, three sensors are embedded in the stator windings. For pole-changing motors with one wind-ing (Dahlander connection), 3 sensors are also sufficient.

9 Pole-changing motors with two windings, however, require The sensors are suitable for embedding 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 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 and DIN 44 082 6 an additional warning is required before the Motor is switched off, separate sensors for a correspon dingly lower temperature must be embedded in the winding.
