Thermal protection<br />
Motor thermal protection with PTC probes<br />
PTC probes integrated in the motor to measure its temperature can be connected to the control card terminals.<br />
Note:<br />
PTC probe protection does not deactivate the motor thermal protection provided by the soft starter calculation. Both types of protection can<br />
operate in parallel.<br />
PTC wiring<br />
(1) Shielded cable is optional.<br />
Characteristics<br />
(1)<br />
Total resistance of the probe circuit: 750 Ω at 25°C (77°F).<br />
Tripping: between 2700 Ω and 3100 Ω.<br />
