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 ratings.
