Ocran asked what is the formula for setting overload relay of a three phase electric motor.?

If one wants to select an ovverload relay to trip off a three phase electric motor with a rated current of 15amps,what formula is to be used.Klockner Moeller states that the rated current is to be multiplied by 0.58..if that's true what's the formula.

And got the following answer:

No general purpose formulas, but just an eye on physics.... Since thermal relays differ to each other, what matters is to have a look to their current VS time tripping curves... If your induction motor frequently starts at full current (5..6 times the rated current), then you can't load it at rated current for long time otherwise windings temperature will exceed the rated one for sure....suggestion is to multiply motor rated current by 0.75..0.80 If you start your motor once per day and then operate at constant torque and power for hours, then you can load r motor up to its rated current being on the safe side...suggestion is to multiply motor rated current by 0.95
