The ”Full Load Motor Current” listed in the tables below are ratings
which determine the proper heat element that should be used with
the EDS Series starters. Refer to motor nameplate for its full load
motor current. It is our recommendation that for normal conditions
the heater element selected should have a capacity of 20 to 25%
greater than the full load current of the motor. This applies to
standard +40 °C (+104 °F) temperature rise motors. For +50 °C
(+122 °F) rise motors, a heater not greater than 115% full load
current should be selected.

However, due to the difference between full load motor currents of
various motor manufacturers of the same size motors, the above
information is approximate.

If selection of heater element is uncertain as might be in the
case of a motor subject to frequent starting and
it is advisable to contact
representative giving full particulars, such as motor horsepower,
voltage, phase cycles, name or manufacturer or pertinent data that
may aid in the selection of the proper heater element.

Determine catalog number as follows:

(1) Select EFD device box catalog number;
(2) Select ”Standard Hub Arrangement

Diagram” number; and

(3) Select symbols that represent hub

sizes from ”Symbol Table.” (Use ”0”
where no hub is required, and separate
the various divisions of the complete
catalog number by dashes.)

Example

The blank body device box selected is
EFD3NL and the hub arrangement is
diagram #8. Hub ”a” is to be 3/4” brazed
threaded; hub ”b”, 1” brazed threaded;
hub ”c”, 3/4” brazed threaded; hub ”d”,
no hub is required; and hub ”e”, 1” brazed
union.
The complete catalog number will be:

EFD–3NL–8–23203E

If a ”Standard Hub Arrangement” is not
suitable for the application, or when hubs
are to be more accurately spaced, submit
sketch locating hubs (1) from centerlines
of walls and (2) from outside back of box
(or from mounting lug surface if lugs are
supplied).

All hubs will be located in centerlines of
walls and evenly spaced unless
otherwise specified.
