Can you please provide LRD overload relay's Cold state and Hot state tripping curve with tolerance?

The LRD tripping curve is provided in the catalog with the 3 phase Cold(1) state, 3phase Hot(3) state, and 2 phase cold(2) state operation. The same is attached herewith for your information and the specific information is highlighted.

If you need higher resolution curve, you will have to use the envelop curve attached herewith, which give you the tripping range time for each current setting point. The tolerances of these curves and the tolerance given for the individual relay curves is +-20%.
