ده مرحله بررسی صلاحیت کارخانه ACB برای خریداران
ACB factory evaluation should compare traceable evidence for the same switchboard duty. Ten qualification checks are provided here; they do not constitute a verified ranking of ten manufacturers.

این راهنمای رفع مشکلات ACB از بین بردن ارتباط بین مشکلات حفاظت و مشکلات متعلقات و مکانیزم.
Follow qualification through delivery
| صحنه | Factory evidence | اقدامات خریدار |
|---|---|---|
| تذکره: | Exact configuration and exclusions | Compare against the common specification |
| Sample | Identity and agreed test scope | Record acceptance boundaries |
| Production | Change and traceability records | Review deviations |
| Dispatch | Matching markings and documents | Complete incoming acceptance |
IEC 60947-2 product evidence and IEC 61439 assembly requirements answer different questions. Plan technical review, inspection, testing, spares and service effort using actual quotations. W9 should be evaluated against the same evidence request as other candidates, without an unsupported claim of market leadership.

Qualify the factory and the quoted ACB separately
بررسی کنید manufacturer identity, exact model, voltage ratings, Icu/Ics/Icw, controller, cradle compatibility, accessories, test-document scope, production traceability and service arrangements. A factory visit can clarify process controls but cannot replace a model’s performance evidence.
| Factory question | Model-level counterpart |
|---|---|
| Who manufactures the unit? | Traceable model and marking |
| How are changes controlled? | Approved drawing and bill of materials |
| What is tested? | Exact report or declaration scope |
| What support is available? | Matching spares and maintenance documents |
Use the same questionnaire for all candidates and keep unresolved responses visible. Factory size, years in business or an export destination list does not establish that the supplied ACB meets the switchboard’s short-time duty.
سوالات متداول
Is this a verified top-ten factory ranking?
No. It is a ten-point qualification framework. Comparative rankings require defined candidates, evidence and scoring.
Can a factory audit replace ACB type-test evidence?
No. Process review and product performance evidence answer different questions. Both may be relevant to the order.
Why check the cradle with the breaker?
Drawout compatibility depends on exact frames, coding and interfaces. Similar current ratings do not establish interchangeability.
What should be retained after qualification?
Retain the accepted configuration, document revisions, unresolved queries and change-control agreement. Link production and delivery records to the approved model.
