Overload Curves Table

[sedat23]

Hello,

I need a values table of the 15 standard Overload curves (attached). If anyone knows the values please post the details.

I would like to plot them in Excel for selection purposes.

Thanks in advance!

Digitize your curve and interpolate for 5, 6, 8, 10, 11, 13, and 14, unless you can get it from the manufacturer. There are no standard values.

Are the numbers 1 -15 just arbitrary numbers or do they have some relationship to the curve, i.e. are they multiples of setting current or something?

They aren't motor overload curves, at least not the standard Class 10, Class 20, Class 30 ones. Where have they come from?

If we learn from our mistakes I'm getting a great education!

This is from a GE Multilin relay.

They have provided a table and formula used in their Manual.

Thanks!
