More Information

Overview Manuals Side Selection Circuit Assignment Documentation Scope Product Applications

Features:

  • Left-side carrier identity: The product marking specifies VERT LEFT SIDE CARRIER.
  • Separated circuit ratings: LocalBus and field-circuit values are printed independently.
  • Exact order control: Model KJ4003X1-BA1 is paired with P/N 12P3831X022 and Rev D.
KJ4003X1-BA1 gives maintenance teams an exact vertical left-side carrier identity for an installed carrier position.

The separate LocalBus and field-circuit markings establish the electrical values that must remain associated with the correct circuit.

The complete model, manufacturer part number and revision marking provide the receiving record needed to avoid suffix or side-position crossover.

For Emerson KJ4003X1-BA1 Vertical Left Side Carrier documentation, quotation and procurement support, Apter Power can help review the complete model, P/N 12P3831X022 and installed carrier position.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Installed side: VERT LEFT SIDE CARRIER makes the left-hand position part of the selection, so housing appearance alone is not enough.
  • Identity pair: Match KJ4003X1-BA1 with P/N 12P3831X022 before accepting the carrier for the planned position.
  • Revision record: Retain Rev D as a receiving and service detail rather than changing the complete model string.
  • Manufacturer check: Use the Fisher-Rosemount Systems marking with the model and part number to resolve a questionable label match.
  • LocalBus path: Keep the 12.6 VDC, 15 A marking assigned to the LocalBus circuit when checking the carrier power path.
  • AC field path: Use the 250 VAC, 13 A value only when the installed field circuit is the labeled AC configuration.
  • DC field path: Use the 30 VDC, 13 A value only for the labeled DC field configuration; it is not an additional LocalBus rating.
  • Rating scope: Treat the values as separate component-circuit limits, not as one combined or cabinet-wide power rating.
  • Label purpose: Use the product marking to identify the exact carrier, side and named circuits, not as a complete installation procedure.
  • Circuit separation: Keep LocalBus and field-circuit values attached to their named circuits throughout the engineering record.
  • Revision handling: Retain Rev D as a service detail without turning it into a different product model or side designation.
  • Instruction boundary: Stop installation until the applicable carrier manual supplies the conditions that are not stated on the label.
  • Vertical carrier assemblies: Use the unit where the installed design calls for the left-side carrier position.
  • Exact carrier replacement: Match an installed KJ4003X1-BA1 and P/N 12P3831X022 record.
  • LocalBus carrier service: Apply it where the carrier position uses the marked 12.6 VDC LocalBus circuit.
  • Field-circuit projects: Retain the separate AC or DC field-circuit marking in the installation record.
Description
The left-hand position is part of the product identity for KJ4003X1-BA1. Its marking combines the exact model with VERT LEFT SIDE CARRIER and P/N 12P3831X022, helping cabinet maintenance and receiving teams distinguish the carrier from other positions or suffixes.

KJ4003X1-BA1 also carries separate LocalBus and field-circuit values rather than one combined power rating. Keeping those marked circuits distinct prevents a procurement match based only on the carrier shape and directs installation review to the exact electrical identity on the unit.

Technical notes
KJ4003X1-BA1 carries separate ratings for the 12.6 VDC, 15 A LocalBus circuit and the 250 VAC, 13 A or 30 VDC, 13 A field circuit. These nameplate values describe different circuits; do not combine them or use them as blanket cabinet ratings, and follow the applicable installation manual.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Is KJ4003X1-BA1 the left-side or right-side vertical carrier?
It is the vertical left-side carrier. The side designation is part of the marked product identity and should remain in purchasing and receiving records.
Which manufacturer number belongs on a KJ4003X1-BA1 purchase request?
Use P/N 12P3831X022 with the complete model. The photographed unit also carries Rev D, which should be retained as a receiving detail rather than added to the model string.
What LocalBus rating is printed on KJ4003X1-BA1?
The LocalBus circuit is marked 12.6 VDC at 15 A. Keep this value assigned to the LocalBus circuit rather than combining it with the field-circuit ratings.
How should an engineer read the field-circuit values on KJ4003X1-BA1?
Treat them as alternative labeled field-circuit ratings: 250 VAC at 13 A or 30 VDC at 13 A. The applicable installation must follow the correct AC or DC circuit and the carrier manual.
What classified-location information is visible on KJ4003X1-BA1?
The unit is marked Class I, Division 2, Groups A, B, C and D, with T4 at Ta=70°C. Those markings apply to the labeled component and do not certify an assembled cabinet by themselves.
Should receiving accept KJ4003X1-BA1 when the delivered carrier is marked for another side position?
No. The required item is explicitly a vertical left-side carrier with model KJ4003X1-BA1 and P/N 12P3831X022; a different side or suffix needs its own approved equipment record.
