Full Voltage

Class 8941

Selection

Duplex Motor Controllers are used to control two motors, and consist of two starters in a common enclosure. Two separate disconnect switches or circuit breakers with operators are included with all combination devices. Unless Form Y68 is specified, an alternation circuit (a Class 8501 Type XO40 relay) is included, which alternately operates first one motor and then the other on each successive closing of a pilot device. Both motors will be energized should a second pilot device close. All devices incorporate a terminal block to simplify wiring of pilot devices A and B. Typical applications include pump motors where a second pump is required for peak demand periods yet alternation is desirable to equalize pump wear.

(replace ●●● with the voltage code)

note

Illustrations may not represent the actual enclosure; they are intended for dimensional information only. Dimensions are in inches.

Footnotes

  1. NEMA 12 enclosures can be field modified for outdoor applications. For details, refer to Class 9991 on Selection.
  2. Replace the three bullets (●●●) in the catalog number with the coil voltage code. Refer to the standard voltage codes listed inCoil Voltage Codes.
  3. The hp rating applies only when dual element time delay fuses are used.
  4. These Forms are most commonly used. Other Forms may be available. Consult the Customer Care Center at 1-888-778-2733 for additional information.
  5. Not available on open style devices.
  6. Single primary voltage must be specified.
  7. Not available on this size. Use Form FF4T●●.
  8. Addition of terminal block 9080CA or 9080GR6 only. A 5–point terminal block is provided as standard for custom connection. A wiring diagram must be provided for factory wiring.
  9. 24 V coil is not available on Size 4. On Sizes 00–3, specifyForm S (separate control).
  10. These voltage codes must include Form S (no additional charge).
