Selection tables are used with the motor service
factor amps if known, otherwise use motor full
load amps multiplied by a factor of 1.15. Select
the heater closest to but higher than the SFA
(motor trip amps).
NOTE: These charts are only for Class 16 Definite
Purpose, Ambient Compensated Starters (identi-
fied by a green reset button) using Quick Trip
(class 10) K heaters for Submersible Motors. Other
Classes or Brands of Starters require different
selection tables, consult the manufacturer for
information specific to that brand/class.
Selection example: Motor service factor
amps = 9. If using a 16AC starter, select a
K49 heater since it is the next higher heater
amp rating number above 9 amps.
① Our current 16F and 16G starters are equipped
with ESP100 adjustable overloads and do not
require heaters. Use this chart only for older
starters requiring K heaters.
