To use this chart: Read up from the ambient

temperature to the curve, and across to find a

correction factor. Multiply the breaker rating by the

correction factor to determine the compensated

rating. Calculate the overloads in terms of the

compensated rating to use the published trip curve.

Do not use these devices outside their specified

operating temperature ranges.
