More Information

Overview Manuals Legacy Fit Converter Service Applications

Features:

  • Legacy hardware boundary: Intended for SAMIs manufactured before December 1992.
  • Rectifier-specific selection: Applies when 1400 V rectifier modules are installed.
  • Traceable ABB identity: Input protection card order code 58424081.
SNAT 7901 58424081 supports a defined early SAMI GS converter configuration rather than the complete ACS 50X population.

The manufacturing-date and rectifier conditions separate this card from later input-protection arrangements.

Using the ABB order code with the installed drive record gives procurement and maintenance teams a controlled selection path.

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.
  • Date condition: The SAMI must predate December 1992.
  • Rectifier condition: The converter must contain 1400 V rectifier modules.
  • ABB order identity: Use 58424081 for the SNAT 7901 board.
  • Later hardware boundary: Do not extend the early-card rule to later SAMI production.
  • Platform: SAMI GS / ACS 50X converter hardware.
  • Module class: ABB lists the card among converter-module components.
  • Voltage group: The applicable table covers the 380 V converter group.
  • 600 V boundary: ABB assigns SNAT 7903 to 600 V converter modules.
  • Before removal: Capture the drive serial and converter-module identity.
  • Before quotation: Establish the manufacturing date from the asset record.
  • Before fitting: Identify the installed rectifier-module voltage class.
  • Stop condition: Do not proceed when either legacy condition is unproven.
  • Lower 380 V ratings: ACS 50X-051-3, -061-3 and -071-3 converter modules.
  • Mid-range 380 V ratings: ACS 50X-100-3, -120-3 and -140-3 converter modules.
  • Higher 380 V ratings: ACS 50X-170-3, -210-3 and -260-3 converter modules.
  • Configuration limit: Only the pre-December-1992 1400 V rectifier arrangement.
Description
SNAT 7901 58424081 is the ABB input protection card listed for selected SAMI GS converter modules in the ACS 50X drive family.

SNAT 7901 58424081 belongs to a narrowly defined legacy configuration: ABB limits it to SAMIs manufactured before December 1992 and equipped with 1400 V rectifier modules.

For maintenance procurement, SNAT 7901 58424081 gives engineers a traceable order identity and a clear hardware boundary before a converter is opened or a replacement is quoted.
Alternative Names
SNAT7901 DFD SNAT-7901-DFD SNAT 7901 58424081
Technical notes
ABB restricts SNAT 7901 58424081 to SAMI units manufactured before December 1992 and fitted with 1400 V rectifier modules. That boundary governs selection: if the manufacturing record or rectifier identity differs, stop the replacement rather than choosing the card from a similar SNAT number without confirmation.

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.
Can SNAT 7901 58424081 be selected for a SAMI GS unit built after November 1992?
No. ABB limits this card to units manufactured before December 1992 with 1400 V rectifier modules; later production needs its documented input-card configuration.
What should a technician do when the build date is missing but SNAT 7901 58424081 is present?
Stop selection until the serial record or asset documentation establishes the manufacturing date and the installed rectifier-module voltage class.
Is SNAT 7901 58424081 suitable for an ACS 50X converter in the 600 V group?
No. ABB assigns SNAT 7903 to the 600 V converter group, so this early 380 V configuration does not apply.
Can the original drive date alone justify refitting SNAT 7901 58424081 after rectifier work?
No. The installed converter must still use 1400 V rectifier modules; record the present hardware because a later modification can invalidate the original selection condition.
What should procurement include when requesting SNAT 7901 58424081 from a legacy label?
Include order code 58424081, the complete SAMI or ACS 50X type, manufacturing evidence and confirmation of the 1400 V rectifier modules.
When should a planner reject SNAT 7901 58424081 even though the connector layout appears correct?
Reject it whenever the pre-December-1992 date or 1400 V rectifier condition is unproven; connector similarity does not override ABB's hardware boundary.
