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).
