ABB 1SDA051368R1 host-equipment fit and acceptance

ABB 1SDA051368R1 is the order-code reference for this breaker auxiliary-contact accessory. Its function is to provide the approved Q/SY state contacts. The common category image is illustrative only; confirm the delivered ABB 1SDA051368R1 by marking and documentation.

Manufacturer identity and key technical data

The ABB 1SDA051368R1 table identifies the manufacturer designation and the series boundary. Do not read an unspecified contact rating, fit dimension or interchangeability claim into the family name.

Decision path before purchase

• Match ABB 1SDA051368R1 to the installed breaker and drawing revision.
• Check T1–T6 frame, 1Q/3Q contact count, SY arrangement and any 24 V DC variant before approving ABB 1SDA051368R1.
• Compare the full ABB 1SDA051368R1 code with the offered package and the job record.

Electrical interface

For ABB 1SDA051368R1, trace the relevant coil, contact or operator circuit back to the approved schematic. Verify supply type and voltage only where the ABB designation and host manual support them.

Do not energize ABB 1SDA051368R1 solely because a connector fits. Isolation, stored spring energy and control-circuit interlocks need site-approved treatment.

Why the host matters

The ABB 1SDA051368R1 accessory must be selected as part of the breaker assembly, not as a visually similar loose component. Record the host frame, mounting form and existing control arrangement.

Where ABB 1SDA051368R1 is being substituted, check the original assembly documentation and each changed terminal, voltage, contact or mechanical detail.

Receipt and handling

At goods receipt, identify ABB 1SDA051368R1 on the package and component; inspect terminals, molded parts and supplied pieces for damage or mismatch.

Quarantine ABB 1SDA051368R1 if the received code, condition or quantity does not match the purchase request. Keep the discrepancy with the maintenance job record.

Mechanical interface

Check the ABB 1SDA051368R1 fixing position, orientation, travel and protection covers. A change from fixed to withdrawable construction, or from one frame to another, can alter accessory fit.

Before fastening ABB 1SDA051368R1, photograph or record the old position and check the supplied parts against the approved assembly instruction.

Installation sequence

After safe isolation, fit ABB 1SDA051368R1 using the applicable ABB breaker instruction and the site's controlled procedure. Recheck conductors, barriers and enclosure clearances.

For ABB 1SDA051368R1, do not treat an unpowered visual fit as proof of an electrically correct release, contact or mechanism.

Functional acceptance

Once ABB 1SDA051368R1 is fitted, prove all assigned contacts and terminal states. Include both normal operation and the relevant inhibited or fault state in the signed test plan.

Record the ABB 1SDA051368R1 order code, host identity, test conditions and observed results before returning the breaker to service.

Future service record

Keep ABB 1SDA051368R1 beside the host breaker asset number and any voltage or pole restrictions in the spare-parts register.

Future ABB 1SDA051368R1 enquiries should quote the complete manufacturer code; a shortened family label is not a safe purchasing specification.
