Performance characteristics are based on room
temperature (77°F, 25°C). Consult Derating curve for
ambient temperatures significantly higher or lower than
standard room temperature.
Example: At 77°F (25°C) the device is calibrated to hold
at 100% of rated current (1) and trip at 135% of rated
current (2). At 140°F (60°C), the same device will hold
at approximately 78% of rated current (3), and trip at
approximately 115% of rated current (4).
