The technical specifications and charateristic curves for each current range can be found on our website
https://library.abb.com/r?cid=9AAC100113&q=TA200DU. For nominal currents between three and eight times the set-
point, the tolerance is +/- 20%
Example for the determination of a suitable overload relay:
The motor with enhanced safety has the following data:
400 V, 50 Hz/60Hz, 77 kW, I
According to the tripping curve below , the trip time is smaller than the time t
