Ambient Compensation Table

To use this chart: Divide 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.
