Ambient Temperature In Degrees Centigrade (°C)  
To use this chart: Read up from the ambient temper-  
ature to the curve, and across to find a correction fac-  
tor. Multiply the breaker rating by the correction fac-  
tor to determine the compensated rating. Calculate  
the overloads in terms of the compensated rating to  
use the published trip curve.
