GE
Heater Selection Information
To
prevent overloading the starter, do not select heater(s) for a motor of larger
rating than the maximum given on the nameplate for the starter. For continuous
rated motors, with a service factor of 1.15 to 1.25,select the heater with
maximum motor amperes equal to or immediately greater than the motor full-load
current (provides a maximum of 125 percent protection). For continuous rated
motors with no service factor, multiply the full-load current of the motor by
0.90 and use this value to select the heater.
How
to Select Heaters
The
table below should be used to determine which column of motor full load amperes
applies for heater selection. Select in order, the base catalog number, the
NEMA type of enclosure, and the column to be used in the proper table by NEMA
size. If full-load amperes of the motor falls between two ratings, select
heaters for the higher rating.
