Trip Curve Diagram


Derating Curve
Approximate Effect of Ambient Temperature on Ultimate Trip


Diagram: 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 110% of rated current (1) and trip at 138% of rated current (2). At 140°F, the same device will hold at approximately 92% of rated current (3), and trip at approximately 120% of rated current (4).
