A China ACB supplier comparison should evaluate exact product and support evidence. Unsupported export totals and broad quality claims do not establish that a quoted авиационный предохранитель fits a particular switchboard.



Check the ACB through the project stages
| Сцена | Required confirmation |
|---|---|
| Technical enquiry | Current, voltage, poles and fault duty |
| Quote | Controller, construction and accessory scope |
| Дизайн | Assembly fit, interlocks and wiring |
| Доставка | Model traceability and document match |
| Передача | Settings, tests and service instructions |
Keep IEC 60947-2 breaker evidence separate from IEC 61439 assembly records and local installation requirements. Evaluate actual logistics, inspection, engineering and spare costs. W9 can be included in a comparable sourcing exercise when it responds to the same exact configuration request as other candidates.
The Руководство по устранению неполадок в системе ACB отделяет проблемы с защитными устройствами от проблем с аксессуарами и механизмом.



Keep product categories distinct
| Quoted item | Evidence to use | What not to infer |
|---|---|---|
| ACB | Exact ACB controller and fault tables | MCCB data do not establish its ratings |
| АВМ | Exact frame and release documents | ACB service features are not inherent |
| Drawout cradle | Approved matching combination | Equal amperes do not prove compatibility |
| Export service | Agreed commercial responsibility | Logistics support is not product certification |
Compare fixed and drawout ACBs when the project requires a documented replacement or isolation procedure.



Compare supplier scope without mixing breaker categories
Ask each supplier for the quoted configuration, controller functions, voltage-dependent fault data and fixed or drawout construction. A molded-case MCCB product mention is not proof of an ACB’s performance. Keep product categories and their documents separate during the comparison.
Confirm responsibility for drawings, assembly inputs, inspection, production changes and spare compatibility. An exporter may support logistics while the manufacturer provides technical evidence; identify those roles rather than treating every sales contact as the testing authority.
Часто задаваемые вопросы
Does an export-volume claim prove ACB quality?
No. Product performance and configuration require exact technical evidence. Trade statistics cannot approve a breaker.
Can an MCCB listing support an ACB rating?
No. They are different device configurations. Use the exact ACB model’s documents.
Should the exporter and manufacturer be identified separately?
Yes where they are different organisations. Clarify responsibility for technical evidence, production, warranty and logistics.
How should suppliers be compared fairly?
Send the same duty and document request to each candidate and record deviations. Compare the complete accepted scope rather than an unsupported ranking.
