Thermal protectionMotor thermal protection with PTC probesPTC probes integrated in the motor to measure its temperature can be connected to the control card terminals.Note:PTC probe protection does not deactivate the motor thermal protection provided by the soft starter calculation. Both types of protection canoperate in parallel.PTC wiring(1)(1) Shielded cable is optional.CharacteristicsTotal resistance of the probe circuit: 750 Ω at 25°C (77°F).Tripping: between 2700 Ω and 3100 Ω.BBV51330 08/2012 25
