More Information

Overview Manuals Assembly Identity Power Interface Service Release Product Applications

Features:

  • Exact device assembly: Rockwell identifies the order number as an 815 A SCR copper and springboard assembly.
  • Suffix-controlled identity: -51-R remains separate from two- and three-device neighboring variants.
  • Drive service boundary: semiconductor, conductor and clamping condition are reviewed together before energization.

The complete 81003-438-51-R order number controls receiving because adjacent suffixes describe different assembly groupings.

Medium-voltage isolation, stored-energy control and exact stack-position records are prerequisites to handling this SCR assembly.

Mechanical stack integrity and electrical checks both have to pass before the PowerFlex drive can be released.

Important Notice: Use the complete 81003-438-51-R product model in every document request.

  • Current class: the OEM description identifies an 815 A SCR assembly.
  • Construction: copper and springboard elements belong to the complete service part.
  • Suffix control: -51-R is not interchangeable by appearance with -52-R or -53-R.
  • Drive position: the installed power-circuit location remains part of the acceptance record.
  • Conductor orientation: copper connection direction and fastening order are recorded before removal.
  • Contact surfaces: cleanliness and damage influence current transfer and heating.
  • Clamping path: spring and hardware condition determine mechanical loading on the semiconductor stack.
  • Insulation boundary: supports and clearances are checked under the drive service procedure.
  • Energy control: medium-voltage isolation and stored-energy verification precede all work.
  • Stack record: component order, hardware and conductor positions are captured before disassembly.
  • Mechanical check: approved fastening and clamping criteria are completed after installation.
  • Electrical check: OEM drive tests and normal diagnostics are required before operation.
  • PowerFlex 7000 power-stage maintenance: replaces the documented single 815 A SCR copper/springboard assembly.
  • Semiconductor stack repair: restores the exact -51-R position after approved isolation.
  • Drive outage planning: order identity and stack records define the required service part.
  • Receiving differentiation: separates the single-device assembly from neighboring -52-R and -53-R groupings.
Description
Rockwell Automation identifies 81003-438-51-R as an 815 A SCR copper and springboard assembly. The -51-R suffix distinguishes the single-device position from nearby -52-R and -53-R assemblies.

In a medium-voltage drive, 81003-438-51-R belongs to a power semiconductor path where device rating, bus connection, clamping and insulation condition all matter. A visually similar SCR assembly is not acceptable unless the complete order number and installed stack position agree.

Replacement work must follow the drive’s medium-voltage isolation and stored-energy procedure. Record conductor orientation and hardware stack-up, inspect contact surfaces and spring components, then complete the OEM electrical and mechanical checks before the drive is energized.

Technical notes
81003-438-51-R is the exact 815 A SCR copper/springboard assembly recognized by Rockwell Automation. Do not merge it with 81003-438-52-R or -53-R; the suffix changes the assembly identity and installed device grouping.

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.
A supplier offers 81003-438-52-R in place of 81003-438-51-R. Can the drive team accept it?
No automatic substitution is established; the suffix identifies a different assembly grouping, so hold it unless Rockwell and the drive record prove equivalence.
What is the first stop gate before removing 81003-438-51-R?
Verify medium-voltage isolation and stored-energy discharge under the drive procedure before touching the power assembly.
Why must the hardware stack-up be photographed?
The copper, springboard and fastening sequence affect contact and clamping, so the exact arrangement must be recoverable.
A replacement fits mechanically but has a different contact-surface condition. Should it be installed?
Hold installation until surface condition and reuse criteria meet the OEM drive service requirements.
Which checks are needed before energizing the drive?
Complete the approved mechanical clamping, insulation and electrical tests, then confirm normal drive diagnostics.
What closes receiving inspection for 81003-438-51-R?
The exact order number, -51-R suffix, complete copper/springboard construction and acceptable physical condition must agree.
