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.
