OVERLOAD CLASS
Use the Class 10 (fast trip) setting for Design E motors,
hermetic refrigerant motor compressors, submersible
pumps, and similar applications, as well as for protecting
general purpose motors where the load permits the motor
to reach rated speed without the overload protection circuit
tripping.
Use the Class 30 (slow trip) setting for special motors driv-
ing high inertia loads such as ball mills, reciprocating
pumps, loaded conveyors, etc.
Use the Class 20 (standard trip) setting for all other applica-
tions. Most NEMA rated general purpose motors will be
protected by a Class 20 setting.
IF A PROPERLY SELECTED TRIP CURRENT SETTING
RESULTS IN AN OVERLOAD TRIP, MOVE TO A HIGHER
CLASS SETTING RATHER THAN TO A HIGHER TRIP
CURRENT SETTING.
Select Class NONE when no overload, phase loss, phase
imbalance, current-sensing, or ground protection is wan-
ted. With NONE selected, the Class W200 motor starter
will behave like a Class W201 contactor.
TRIP CURRENT SETTING
The overload trip current of an Advantage starter is deter-
mined by its program and its DIP switch settings in Positions
5 through 1 as shown in Tables IV and V. Use only the table
appropriate for the starter involved and disregard the other.
For motors with a marked temperature rise of not over
40
o
C or with a service factor of not less than 1.15, find the
range of motor FLA in Column A that includes the FLA of

See Tables VI and VII for selection of appropriate short
circuit protective device.
the motor to be protected and use the setting shown for
DIP switch Positions 5 through 1. For all other motors, sel-
ect a range in Column B.
Settings based on Column A give a trip rating of not more
than 125% of motor FLA. Settings based on Column B give
a trip rating of not more than 115% of motor FLA.
