for IEC contactors, Wye-Delta Start
The chart below shows the motor full load amps
(first column) and the calculated value for Wye-
Delta start (second column). To calculate this
value, the full load amp rating of the motor is
multiplied by .58. This value is used to determine
the overload relay used. For example, 60 (FLA) x
.58=34.8. From the second column in the chart,
see the value 34.8 and select 12835 overload
relay. The overload relay has a dial on the front
that must be set to the calculated amp value.
