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.

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.
