Santerno Sinus Penta - Table 119: Typical Datasheet for 4-Pole, 50 Hz-400 V Motors

SINUS PENTA
PROGRAMMING GUIDE
388/486
The following formula can be applied:
LRC x LRT
IEC Class = -------------
FLC x 6
Once the approximated IEC class has been calculated, use the motor thermal time constant (C267) that corresponds to
the closest IEC class from
above.
Example 1a: the 7.5kW motor in the table below can be approximated to have a trip class of:
820 x 20
IEC Class = ------------- = 27.3
100 x 6
The motor thermal time constant that you would select is IEC class 30, C267 = 1080s.
NOTE
A
s an even quicker guide, the IEC trip class can generally be approximated as the
locked rotor time.
