Figure 4-1 Pt1000 characteristic
High short-term overload conditions require additional protective measures as a result of the
thermal coupling time of the temperature sensor.
Note
Temperature ev
aluation using only a Pt1000 does not guarantee full motor protection.
NOTICE
Destruction of the motor for a thermal critical load
A thermally critical load, e.g. high overload when the motor is stationary, can destroy the
motor.
• Employ additional protective measures, e.g. an overcurrent relay.
