Approximate Time — Current Characteristics at 77°F (25°C)
Approximate Effect of Ambient Temperature on Ultimate Trip
Performance characteristics are based on room temperature (77°F). Consult derating curve at left for ambient temperatures
significantly higher or lower than standard room temperature.
Example: At 77°F the device is calibrated to hold at 100% of rated current (1) and trip at 135% of rated current (2).
At 140°F, the same device will hold at approximately 78% of rated current (3), and trip at approximately 115% of rated current (4).
