Description
Bulletin 120E multi-speed starters are designed to control “two-speed,
separate-winding” AC squirrel-cage induction motors. These starters are available for
constant torque, variable torque or constant horsepower three-phase motors. Multispeed motors are commonly used on machine tools, fans, blowers, pumps, conveyors
and many other types of equipment.
Bulletin 120E multi-speed motor starters use Bulletin 100 contactors and Bulletin 193
bimetallic (Class 10) or solid-state overload relays. A normally open auxiliary contact
is also included on each contactor. A wide variety of factory- and field-installed options
are available.
For two-speed consequent-pole motor starters, consult Allen-Bradley Sales Office.
Constant Torque — Constant torque motors will supply a constant torque at each
speed while the horsepower rating will vary directly with the speed. Typical
applications include conveyors, compressors, hoists, mixers and milling machines.
Variable Torque — Variable torque motors have horsepower ratings that vary as a
square of the speed and have torque ratings that vary directly with the speed. Typical
applications include centrifugal pumps and fans.
Constant Horsepower — Constant horsepower motors have the same horsepower
rating at each speed while the torque varies inversely to the speed. Typical
applications include mixer, milling machines and cranes.

✪✪ Overload Relay Code ➊
The Cat. No. as listed is incomplete. Select (2) overload relay codes from page 3-87 or 3-88.The first code will denote the high speed overload
relay, and the second code will denote the low speed overload relay.
➊ For single-phase (1∅) applications, consult Allen-Bradley Sales Office for overload relay selection.
➋ When selecting a factory-installed control circuit transformer (see Modifications page 3-98), use the Common Control Coil Voltage Code to denote
the transformer primary voltage. The starter coil and transformer secondary voltage will both be 120V by default. Example: Cat. No.
120E-C09FB✪✪-6P will have a transformer with a 480V primary/120V secondary and a 120V starter coil. If a starter coil voltage other than 120V
is desired, a second Coil Voltage Code must be added to denote the coil/transformer secondary voltage. Example: Cat. No. 120E-C09FBJ✪✪-6P
will have a transformer with a 480V primary/24V secondary and a 24V starter coil.
➌ Coils below 110V are not available for 120E-B400 and 120E-B600 Starters due to high inrush current.
