Calibration of the thermal relay
The thermal relay serves to avoid damage to the motor due
to an excessive absorption increase or if a phase is missing.
Refer to the table in wiring diagram 6 od Appendix A for the
calibration.
The protection is in any case ensured even if the minimum
value of the thermal relay scale is over the rating absorption
of the motor. This occurs when the motor power supply is
400 V.
To release in the event the thermal relay has cut-in, press
