This curve is to be used for application and coordination purposes only.
The EZ-AMP overlay feature at the bottom of the page should be used
during coordination studies.
All time/current characteristic curve data is based on 40°C ambient cold
start. Terminations are made with conductors of appropriate length and rat-
ings.
