1. LED - This LED idicates an overload
condition is present. It will light if the
continuous current is 85% of the Ie Setting
for a 38 second duration.
2. Ie-Continuous Current Setting. Continuous
Current Values for each lettered setting are
indicated by the chart shown at the left.
Please select the value closest to the
Motor Nameplate Full Load Current (FLA).
The circuit breaker will trip when the current
exceeds 115% of the Ie Continuous Current
Setting. A "Thermal Memory" effect prevents
the breaker from being re-energized.
